Gregory Baltoro 65L Backpack Review

Hiking along the rocky shoreline of the Poudre River, the uneven terrain had me teetering back and forth as I made my way toward the river’s edge. Normally, I wouldn’t take such a tenuous approach with a heavy pack on my back, but the new Baltoro 65L carried the weight so effortlessly that I almost forgot it was there.

Arriving at the river’s edge, I slung the pack off my back and reached with one hand into the mesh dump pocket for my water filter while the other pulled my bottle from its sleeve.

It’s no wonder the Baltoro has been one of Gregory’s flagship packs for 20 years. Its ability to efficiently carry loads, the ample storage options, and bombproof build make it a solid contender for almost any kind of backpacker (except ultralighters). The burly design is great for long trips with heavy loads. That’s why GearJunkie named it the Best Heavy-Hauler Backpacking Pack in our guide to the Best Backpacking Backpacks.

In 2026, Gregory released an updated version of the Baltoro 65L. Supposedly, it fits hikers better and offers improved breathability and stability for long hikes and backpacking trips. I wanted to test those claims, so I took the new Baltoro out for a test run in the foothills of the Colorado Rockies.

So far on my hike along the Poudre, the pack was proving to be a very functional and comfortable piece of gear.

In short: The Gregory Baltoro 65L Backpack ($370) is designed specifically for carry comfort and larger loads. The 2026 version refined the pack’s fit, added breathability, and improved stability. It uses Gregory’s FreeFloat A3 Pro suspension system, has 3D Shoulder Harness & Hipbelt Construction, and AirCushion backpanel for max ventilation. Backpackers who don’t mind adding ounces for improved comfort will appreciate what Gregory has brought to the table here.

Weight

The first thing you’ll probably notice when you pick the Baltoro up is its weight. Empty, the small weighs 4 pounds, 11.5 ounces; the medium weighs 4 pounds. 14.7 ounces; and the large (tested) clocks in at 5 pounds, 4 ounces. It is the second-heaviest pack on our guide to the Best Backpacking Backpacks.

If weight is a priority and ounces matter to you, the Baltoro is not what you’re looking for. But, for those who value comfort and the ability to pack more gear, it’s a solid pick. The technology that makes it so comfortable to carry is largely responsible for its heavier weight. For some, that’s worth the tradeoff.

Construction & Materials

The pack features Gregory’s FreeFloat A3 Pro suspension system paired with its 3D Shoulder Harness & Hipbelt Construction. That helped prevent rubbing or chafing on my hips and kept the pack snug against my body while still allowing it to move independently.

Stiff packs tend to wobble with each step, but Gregory’s packs articulate with your body’s movement to provide a smoother carry. The Baltoro was no different in this regard.

The pack is compatible with an internal hydration sleeve. Specifically, you can pair the patented SpeedClip hydration hanger with Gregory’s 3D Hydro Trek reservoir for a seamless hydration system.

Gregory used a 210-denier nylon and a 420-denier nylon coated with PFAS-free C0 durable water repellent (DWR) in the construction. It isn’t waterproof, but it will shed water for a short while if you’re caught in a drizzle. It is also very durable and resistant to tearing and abrasion.

Pockets Galore

In addition to the padding and comfort, hikers will immediately notice the pack’s many pockets. The front of the pack has dual zippered pockets with a floating divider wall, a mesh-stretch shoulder-harness pocket, and a large side fabric stuff pocket with a pass-through. There is even a front U-Zip zipper that accesses the main body of the pack without using the top drawstring access. That’s huge for on-trail accessibility.

The brain of the pack has a large zippered compartment in the floating top pocket, a small quick-access pocket, an underside zippered pocket, reflective attachment points, and a key clip.

And if that’s not enough, there are also bottle-holster pockets. One drops down and can easily be tucked away if needed. The other has a Velcro closure on the side for one-handed, on-the-go access to water bottles. The tops of both have a secure bungee closure for all bottle types.

The hip belt has large zippered pockets big enough for a cell phone, and the sleeping bag pocket at the bottom has its own zippered compartment with a removable divider.

The Baltoro has so many pockets and storage options that I wasn’t always sure where to put what. But I never lacked space. This pack carried everything I needed with ease.

Gregory Baltoro Upgrades

When putting the Baltoro to the test, I really parsed out what has changed. The brand told GearJunkie that it redesigned the pack to deliver “a more refined fit, added breathability, and stability.”

The FreeFloat suspension system adds a flexing hipbelt and auto-rotating shoulder harnesses for a dynamic carry. You can see this just by looking at the pack. The padded waist belt is massive and pivots with the wearer, independent of the pack’s body, and more in synch with yours. The shoulder straps do the same, making it feel like an extension of your body as you hike.

Gregory also added a new AirCushion backpanel. The panel is supposedly 90% air for enhanced breathability and temperature regulation. The airflow helps keep you cooler while backpacking, especially on hot days. Your back will still get sweaty (trust me), but the ventilation certainly helps a lot and dries out very quickly.

Lastly, Gregory updated the Baltoro with added “enhanced design features.” Those include a new front-and-side pocket design with more durable fabrics for long-term abrasion resistance, and a quick-access water bottle pocket with enhanced durability and water bottle security.

Sizes & Volumes

The Baltoro comes in small, medium, and large, and Deva (the women’s version) is available in extra small, small, and medium. Both feature an adjustable torso to dial the fit to your body.

While the men’s Baltoro is available in 65L, 75L, 85L, and 100L volume options, the Deva comes in slightly different volumes. It is only available in 60L, 70L, and 80L volumes.

Room for Improvement

As mentioned, the Baltoro is somewhat heavy for its size, which could count against it to some.

The lack of a rain cover is also kind of a bummer. Yes, it’s coated in a PFAS-free DWR, but for $370, Gregory should include a rain cover with this pack. If you’re caught in a downpour, that DWR coating won’t stop your pack (and everything inside of it) from getting soaked.

Gregory Baltoro 65L Backpack: Who’s It For?

The Baltoro backpack is designed for backpackers who are more than just weekend warriors. These packs are intended for the long haul. The 65L Baltoro I tested is ideal for 3-5–day backcountry trips. With the 75L and 100L versions, you could stretch that even longer.

At the same time, this pack is bombproof, built with durable materials and boasting sturdy construction. It has more storage options than you need, and the 2026 version features new technologies that improve carry comfort, breathability, and overall functionality.

If you are a minimalist backpacker who cares about counting ounces, the Baltoro is not for you. However, if you’re looking for a burly, high-volume pack that will last years and survive harsh backcountry use, it’s a perfect pick.

The Baltoro is an investment at $370, but you also won’t need to worry about it on the trail. You can load it up, beat it up, and know it will be good to go for the next adventure.
