The Best Merino Wool Shirts of 2026

Senior Editor Nick Belcaster wore the Ibex Naturalist Short Sleeve Crew ($90) for a month this summer, and aside from the screen-printed interior logo wearing off, it survived admirably. That’s an impressive thing to say about a 100% merino wool shirt, which provides the full measure of wicking and temperature-regulating properties, but frequently at a ding to durability. Not so with the Naturalist.

Yes, $90 is top dollar for a T-shirt, but this is also one of the softest 100% merino options we’ve worn to date. Made from 18.4-micron Australian merino, this tee uses slightly thicker fibers than other tees that blend with nylon to help shore up that durability. The 165 gsm fabric is solidly in the ‘all-around’ category for wear, and was comfortable for both everyday wear and more active pursuits like hiking.

During testing, the feature that stood out the most was the stitching used to mate the panels of the Naturalist. The shoulders are joined with a saddle stitch, which is more commonly used in leather craft, and is highly resistant to abuse as it won’t unravel, even if a thread is snagged. Across an entire month of all-day use, Nick couldn’t find a single issue with the stitching on the Naturalist.

This T-shirt isn’t magic, of course, and during use, a few stains did accumulate (a splotch of 10W-30 oil on the sleeve was the worst). Laudering is a little more involved with merino wool apparel, so make sure to wash cool and hang up to dry shirts like the Naturalist. After our wear test, the only true permanent damage was that the screenprinted logo on the interior of the shirt had worn away. For 30 days of non-stop use, we’d argue that’s pretty good.

$90 is just about top dollar for a merino wool Y-shirt, but the Naturalist is well-deserving of the spend. The 100% merino is one of the softest we’ve worn, and Ibex is about top of the heap when it comes to doing the most with wool.

While other wools can be as coarse as 40 microns (think itchy grandma sweaters), merino wool can be as thin as 24 to 15 microns, which is exactly why the Ridge Merino Journey and Wander Merino Wool Shirts ($65) — made with 17.5-micron merino — are so dang buttery smooth. And at $65, these tees slide in far below other comparable merino shirts. Now a few seasons into wear, we can confidently anoint the Ridge Merino tees to the best value in our review.

Having crafted an entire line revolving around sheep’s clothing, it’s clear that Mammoth Lakes-based Ridge Merino certainly has a thing for good wool. The Journey tee is easily one of its most popular, and we found it’s for good reason. This tee is just all-around cozy, and the 17.5-micron merino is finer than even our top pick, the Icebreaker Tech Lite III.

Sewn with a double-stitched neck and sleeves, the Journey felt like it was made for the long run in our testing. Couple that with the nylon core-spun merino textile, and you’ve got a durable merino piece that’ll keep up for as long as you wear it. When holding a nylon-merino hybrid tee next to a full merino cut, we noticed that the blend has a good bit more stretch and that it bounces back with little bagging.

There’s also no external branding on this tee, which is something we’ve actually come to appreciate. The look isn’t as travel-ready as the sleeker Unbound Merino Crew Neck, but it’s nice not to feel like a billboard when you’re stepping out for a jog.

We particularly liked the cut of this tee, which is a bit slimmer and longer, though washing and drying will shrink it to some degree. This can cause a little confusion when trying to find the right size, but thankfully, Ridge Merino provides a sizing chart to assist. Across three different testing team members, we all were able to get into a size that fit perfectly.

When comfort is king, but price is still a consideration, the Journey and Wander Merino Wool Shirts are high on our list of most cozy merino wool shirts.

The Woolly Everyday Crew Tee ($68) was the first piece we tried from the brand, and color us impressed — this is one excellent merino T-shirt. Add to that the stellar price — only the Ridge Merino tees are cheaper, but also not 100% merino — and you’ve got an excellent value option.

The 175 gsm fabric is a bit thicker than the 145 gsm Ridge Merino tees, meaning the Everyday Crew is better for, well, every day. The thinner Journey and Wander tees are poised as activewear, while the first time we wore the Woolly was on a flight to Argentina (where it landed in Buenos Aires funk-free). Being a 100% merino cut means that holes will appear a bit quicker on the Woolly tee, but the thicker weight fabric is an excellent way to prolong the shirt’s lifespan.

The 100% merino weave comes from Australian flocks, and the material is RWS certified, which gives us peace of mind (and demonstrates that you can provide solid, full-merino clothing without compromising on animal welfare). The material is supple in hand and thick enough to feel that it won’t start to thin out in the common areas (hemline, tops of shoulders). After three weeks of tough travel abroad, this tee was still going strong.

The seam line across the tops of the shoulders isn’t ideal for long stints under a pack strap, and we prefer raglan sleeves in our more active cuts. That said, the Everyday Crew doesn’t claim to be overly sporty, and it’s a minor detail. We still put the Woolly to work on a few hikes under a light daypack, and it did perfectly.

It’s tough to get a 100% merino tee for less than $80, so for $68, the Everyday Crew tee feels like a steal, but doesn’t wear like one. The Ottie Merino Tees are close to the same price, but the Woolly options are much easier to get your hands on, making this our top pick in merino value.

Unbound Merino says, “We want you to pack and own less,” and the brand’s Merino Crew Neck T-Shirts ($95) make that vision possible. With a classic cut, versatile color palette, and no visible logos, this 100% merino tee is an ideal travel shirt. 

Perennial traveler Katie Griffith wore this top for 5 days straight while hiking, climbing, running, and going out for drinks. Even after working up a sweat several times in the sun, the Merino Crew Neck held very little odor, especially when compared to a cotton tee.

We were also impressed by the wrinkle resistance after days of use. The 17.5-micron merino is so comfortable that we fell asleep in this shirt several times and just continued wearing it the next day. 

The 190 GSM fabric weight is a little heavier than most others we’ve tested, but we found this to be a benefit in cool airplane cabins, where we often look for a little more insulation. Worn side-by-side, we could certainly feel the difference between this tee and something lighter like a 120 gsm tee. Sizing is spot-on for travel as well, with a classic fit that incorporates a good amount of drape. This is also one of the only merino tees we’ve tested that comes in specific tall sizes.

We also appreciate Unbound’s commitment to ethical production alongside quality, with wool sourced from mulesing-free wool farms in Australia. Mulesing is a controversial practice that involves removing skin from a sheep’s hindquarters to prevent parasitic infections. Unbound’s production facilities are also WRAP (Worldwide Responsible Accredited Production)- certified, and its merino is Woolmark-certified. 

Unfortunately, the price of this premium tee has crept up since our last encounter, and at $95, it is at the upper end of the merino tee spectrum. Compared to something like the Icebreaker Tech Lite III, that extra $5 nets you finer 17.5-micron wool, but otherwise it’s tough to split hairs between the two.

Unbound warns to never tumble dry this top, making it a little more high-maintenance than some merino shirts. Though with its excellent odor resistance, you’ll rarely have to wash it. With its simple design, it can easily transition from sightseeing or hiking to an evening out. If you want to pack a single t-shirt for a week-long trip, look no further than the Unbound Merino Crew Neck.

The Ridge Merino Solstice Pro Lightweight Wool Hoodie ($100) is the updated version of our previous choice in best merino sun hoodies, and it’s only been improved. The ‘Pro’ version gains a half-zip on the front, along with a chest pocket for wrangling small essentials, and both additions are well worth it in our opinion.

That half-zip works wonders in combination with the hood, which is a little less baggy than the regular Solstice Hoodie, and better for more active pursuits (think a better hood for biking, etc). With the zipper down, you get a crazy amount of ventilation moving through the piece, and it’s ideal for grinding out some elevation.

The chest pocket has also become a near-essential in our testing, and while it’s a bit snug for modern cell phones, you likely don’t want to store your mobile there anyway. The pocket is better suited to chapstick and the like, and the low-profile zipper keeps the design out of the way when movement is the goal.

The hoodie is still made with the same ‘(m)Force merino’, which is a 87% 17.5-micron merino wool, 13% nylon blend that the brand’s Journey and Wander tees use. We think the blend is just about the perfect compromise between full merino capabilities and adding a bit more durability by drafting the wool around the nylon core.

The Solstice Pro is certainly a more summer-oriented hoodie at 150 gsm, and breathes excellently when working hard in it. If you’re after something a bit warmer for a wider temperature range, the 185 gsm Ibex Indie Hoody is quite a similar cut (all the way down to the half-zip), and is better for when cold winds start to pick up in October, or ski touring in the depths of February.

If you’ve got to have just one merino wool hoodie, however, we think that the Solstice Pro is the way to go. It’s $75 less than the Indie, is a better everyday weight, and the hood is more accommodating. Snag this one if you’re looking for a full-coverage merino option.

Now in its third iteration, we’re still on team Icebreaker Merino 150 Tech Lite III ($90) when it comes to the best merino tees around. This 150-weight tee is primed for warm weather and physical activity, and even though the fit is slightly let out in the torso in this version, we’re still convinced it’s perfect for everything from the gym to the jetway.

As a full 100% merino tee, there’s no hiding the true properties of the wonder fiber here (though you will need to treat it a bit nicer), and the 18.9-micron fiber used in the Tech Lite III is right on the line between fine and superfine merino. Sliding this new tee on for the first time, we were reminded of why we loved the previous version so much: a supremely soft touch. From mountain bike laps in British Columbia to rainforest hikes on the Olympic Peninsula, it performed flawlessly.

This new version of the Tech Lite has a slightly less athletic cut than the previous one, with a slightly baggier fit in the torso. Some will love this, while others who appreciated that cling may want to pivot to something else, like the Patagonia Capilene Cool. We found it to be a better all-around fit that felt a little more casual, and as a bonus, the updated version gains improved shoulder seams that are stronger than our last tee.

Now, obviously, opting for a full merino tee will come with some durability shortcomings, and, indeed, nearly every wool tee we’ve tested has eventually developed a few holes through use. The Tech Lite III is no different, and while surveying the damage after a full week in this tee, we found two small holes in the torso. That’s just the way it goes, in our opinion, and we found that laundering this tee on a gentle cycle was a good way to slow the process.

$90 is about the going rate for a quality merino tee like the Tech Lite III these days, and is even a bit competitive when compared to the $100+ you might spend on a full merino sun hoody. If you’re after the genuine article (and are willing to trade a bit of longevity for performance), there’s nothing quite like a full merino tee, and we think the Tech Lite III is one of the best you’ll find.

The brand doesn’t make just socks, and the Smartwool Merino Short Sleeve Tee ($95) is proof of that. This all-arounder moisture-wicking tee kept us cool on warmer-weather hikes but also offered good coverage.

This layer is a super-comfortable piece at a reasonable price and is now more sustainably made. In terms of construction, we like that it is made with 88% merino with a nylon-spun core, striking a good balance between soft and durable.

This puts it in good company with other blended tees we’ve tested. Shirts like this are better for the long haul, but they won’t get the full measure of merino performance because of it.

We also like that the layer was durable when packed, worn, and washed multiple times over the few months we tested around Colorado. This tee has a lot to offer while still being reasonably priced, making it a great option for those who want a more budget-friendly tee.

Despite loving that this tee runs taller for those with a longer torso, we did discover that the sizing for different body types was a bit trickier than other tees we’ve tested — possibly due to some versions of the tee being colored with plant-based dye. It’s also good to note that these colorways have an added ‘On-of-a-Kind Plant-Based Dye’ logo that runs on the hem, which can be a turn-off for some folks.

While this tee gives the Icebreaker Tech Lite III a good run for its money, we feel that if you’re going to have just one, it should be the real deal and 100% merino. This isn’t to say that we don’t love blends like the Smartwool — they are nigh essential for pieces we plan on wearing into the ground — but it’s tough to explain the luxurious feel of pure merino until you’ve tried it. For this reason, we recommend folks grab the Tech Lite first, then a blended tee like the Merino Short Sleeve for more contact sports.

As a general tee, however, the Merino Short Sleeve Tee certainly lives up to every part of its name.

The KÜHL Cashmerino Short Sleeve Tee ($80) is a straightforward, highly adaptable shirt. It is light and breathable enough for high-output days, but the clean aesthetic doesn’t look out of place off the trail. For a single layer that transitions easily from a backcountry approach to everyday wear, it is a practical option.

The shirt is built with a fine 16.5-micron New Zealand merino wool, which gives it a soft hand-feel and eliminates any scratchiness. Tester Katie Griffith wore this tee while rock climbing, running, and hiking to see how it handled temperature regulation and abrasion. Pure merino can be fragile, so KÜHL spun the wool around a nylon core. That blend adds necessary durability, holding up well against coarse rock faces and heavy backpack straps without showing premature wear.

Griffith did the bulk of her testing in the arid climate of Joshua Tree, California, which highlighted the shirt’s main quirk: static cling. On dry days, the lightweight fabric tended to stick to the body. However, once she worked up a sweat on a climb or a run, the moisture dissipation resolved the static issue.

The fit is regular rather than overly athletic, so it pairs just as well with jeans as it does with running shorts. For minimalist travelers or anyone looking for a durable, multi-use merino shirt that handles both high-sweat tracking and casual wear, the Cashmerino Tee delivers reliable utility.

The Ibex Indie Hoody ($175) is another stellar merino sun hoody that’s earned a spot in our closets. This 100% merino cut fits snugger than the Ridge Merino Solstice Pro Hoody, making it a nicer layer to run beneath others, and we’ve broken it in while backpacking, ski touring, and even international travel.

At 185 gsm, the Indie is a bit thicker than the 150 gsm Solstice Pro, and in testing, we leaned on it more for slightly chillier days and locations, such as trekking in Patagonia most recently. Thankfully, the hoodie has a quarter zip, which makes for easy venting when the sun comes out, but even being slightly thicker, the hoodie still sheds excess heat well.

The construction of the Indie is classic Ibex, and everything seems to have been thought of. The flat-lock seams lie low and don’t rub us the wrong way when worn under a backpack, and the raglan sleeves keep stitch lines off our shoulders. The sleeves are the perfect length for wearing with or without the thumb loops, which are robustly built and give us confidence we won’t blow through them.

The hood is snug and thin enough to run underneath a bike helmet, which also helped make the Indie feel just a bit warmer. Over the time we’ve worn it (one year now), the hoodie itself has accumulated some small holes — on the shoulders and sleeves — but nothing out of the ordinary. This is always a consideration with 100% merino apparel, but a great way to stave it off is by going slightly thicker with the material, and the 185 gsm cut on the Indie works wonders.

At close to double the price of the Solstice Pro hoody, we think the Ridge Merino piece is still the better buy for those looking for a merino sun hoody. That said, the 100% merino blend used in the Indie Hoody is enough to sway purists. This is one solid sun hoodie.

Our resident travel guru took the Proof 72-Hour Tee ($84) to Japan recently, where it proved a worthy travel companion (and stayed stink-free in the process). This merino blend tee from Huckberry’s internal brand is a great travel option, and we put it up there with our top picks.

Aiming to be travel-ready, the 16.5 micron merino wool (sourced from Australia and New Zealand) is blended with 13% nylon to give it a slightly more robust durability and live up to the ‘72-hour’ moniker. This is similar to NuYarn and other blends we’ve reviewed, and we can attest that adding even a small percentage of nylon makes a difference.

As our traveller Steve Graepel says, “The look wears less mountain town and more everyday,” and we think that’s a good thing: it’s easy to go from the plane to jumping on a work call without needing a full wardrobe change. The fit on the 72-Hour is offered in both a regular and slim, so consider this when making your sizing choice. 

Sizing for men runs from XS to 3XL, so most should be able to tuck into a tee (though we will note that this shirt is only offered in a men’s cut currently, as that’s Huckberry’s whole deal.) Still, that covers about half of the human population, but we would love to see a female silhouette offered somehow.

Obviously, this won’t be the first merino tee you’ll jump into for a run (look to the lighter 115 gsm Artliect Sprint, for that), but for a few bucks less than our top travel pick, we think that the 72-Hour Tee is a killer alternative option. The choice of whether you snag a regular or slim fit is enough of a reason for us to consider even grabbing both.

Testing the Patagonia Capilene Cool Merino Shirt ($75) exceeded our expectations, especially for the price. This shirt is a blend of 65% RWS-certified merino wool and 35% polyester, which kept us cool — as the name suggests — while hiking in balmy summer temperatures. Yet when we added another layer, it kept us comfortable when the air got chilly.

Another thing we appreciated about this shirt is how lightweight, airy, and not quite as sheer it is as other merino tops — making it an easy standalone top for various activities. Additionally, after wearing it all day and underneath a pack while backpacking, it stayed surprisingly odor-free. In fact, it easily made it on our list of go-to shirts for multiday excursions.

Unfortunately, this top isn’t perfect. We found signs of pilling and snags after a couple of washes. However, given its reasonable price and the fact it requires fewer washes in between wears, we still like it. And since it has a sizable percentage of polyester, it’s not exactly as soft as other 100% merino shirts, but still, we think it’s pretty soft considering.

For a budget merino shirt that has a higher percentage of wool, consider the Ridge Merino Journey and Wander shirts as excellent alternatives. We’ve noticed that our version of the Capilene Cool shirt has held up better in the long run, but the trade-off in breathability is noticeable compared to the higher merino percentage of the Ridge Merino cuts.

If you want a shirt that fits comfortably, doesn’t impede mobility, is versatile in both cool and warmer temperatures, and is reasonably priced, then the Capilene Cool Merino Shirt is a strong contender, in our opinion.

The Voormi River Run Hoodie ($139) is made of 100% merino wool, but with a unique blend and construction. This USA-made hoodie uses an ultralight Precision Blended Wool, a fabric weighing under 100 g/m². That’s 30-50 g lighter than the leading merino fabrics currently on the market, Voormi claims.

When packing and when wearing, we can attest that this hoodie is light. In fact, it’s so light and versatile that we’re not sure where we haven’t worn this Voormi layer — paddleboarding, camping, climbing, snowshoeing, kayaking, hiking, and running errands. And with the amount of time spent under the sun, the UPF 50-rated protection of this sun protection shirt is a welcome feature.

So what are our cons? It’s crazy ultralight and soft, meaning it’s prone to snag easily, which also doesn’t bode too well with the high cost. But ultimately, with the amount of wear this hoodie has gotten, it’s well worth the investment. If you’re after a merino sun hoody that’s got a longer lifespan (at a very slight weight ding), the Ridge Merino Solstice Pro Hoody is highly comparable and a bit less liable to snags.

The River Run Hoodie was designed with everything from fly fishing day trips to multiday river trips in mind, which is one of the main reasons we love it so much. If you are heading up into alpine territory or looking for a merino base layer for fall, we think it’s a good choice for that as well.
