The award-winning Gregory Baltoro 75 internal frame backpack boasts a wealth of access points, an array of trail-worthy features and an innovative, custom-fit suspension system that combine to make this 4300+ cubic inch pack a backcountry workhorse.

Gregory has equipped the pack with the high-performance Response A3 suspension system. Designed to flex with the natural movements of your body, a “wishbone” aluminum alloy wire frame works in tandem with anti-barreling support to help distribute weight evenly and provide superior load stability, comfort, and range of motion. A composite EVA foam backpanel offers breathability and support while resting comfortably against your back. Extensive, contoured padding in the harness, lumbar area, and hipbelt further enhance both fit and comfort. The pre-curved shoulder straps and hipbelt fins move independently of one another to mirror your every movement on-trail or off. These components are available in varying sizes, allowing you to properly customize fit. If you require customization of components, please leave detailed instructions about what size hipbelt and/or harness you need in the “Order Comment” field on the “Order Review” screen at checkout or call us at 1.800.617.0643 to place your customized order directly with one of our Gear Specialists. A sternum strap and load-lifter straps further enhance the pack’s fit and ensure the stability of your load.

A lashed divider separates the top and front-entry main compartment of the pack from its lower sleeping bag compartment, allowing for organization and separation of wet and dry gear. When hauling longer items or in need of access between the two compartments, you can open the divider and convert the pack to a single, large compartment. An extendible lid includes zippered pockets for stowing gear and can be detached entirely to save weight.

Other features include an enormous front stretch pocket, zippered side bellows pockets, a canted, hideaway water bottle holder, two zippered hipbelt pockets one of which is entirely waterproof, gear attachment loops, trekking pole attachments, a front harness quick-stow feature for sunglasses, and side, cross over and lower panel compression straps. Gregory also includes a raincover for full protection against the elements. An integrated sleeve and exit port make the pack hydration compatible (hydration system sold separately). That same sleeve can be removed entirely and, thanks to its integrated minimalist shoulder straps, it can be used as a lightweight daypack or summit pack!

The Gregory Baltoro 75 backpack is available in your choice of colors and Small (best fits torso lengths ranging from 16”-18”), Medium (18”-20”) and Large (20”-22”) size options.

Reviewed by Alex E. - November 9, 2018

Likes: This is a very comfortable fitting pack. It feels a little stiff new, but once I wear into it I can really see myself enjoying it. It's a great size to split a 3day load with someone else with a pack.

Dislikes: N/A

Great product! Be sure to verify the right fit
Reviewed by TPL - October 15, 2018

Likes: Comfort, intuitive and thoughtful design, Looks sharp, good mix of functionality and durability. I actually ended up purchasing a L last years model at closeout, then went in to a local retailer for a fitting and found that a small rather than a large fit my frame better. At 6’, 190, I’m usually a large or at minimum medium, but a fully loaded (35lb) small actually fit my frame, shoulders and hips best. I opted to get the 2018 model, with the improved breatheability, slightly lighter weight, and small refinements (like the sunglass holder on the L shoulder strap). I will need to return the 2017 large, as it does not fit me well. I’m looking forward to putting this through the paces with some 3+ night backpacking trips. I was considering the Deuter and Osprey, but settled on this for being the best combination of size, features and function.

Dislikes: Be sure to check size before ordering

Workhorse Pack
Reviewed by Michael - October 10, 2018

Likes: Great pack for extended trips with everything you could possibly need. Handles weight extremely well. Found this pack to be far more comfortable than competitor packs in the same category.

Dislikes: Wish that the removable day bag was similar to competitors (removable top) as opposed to a hydration bladder holder and that hydration bladder storage was kept separate similar to comparable competitor packs. None of this was a deal breaker, but would make the bag that much better.

Very well made
Reviewed by Hsing-o L. - October 1, 2018

Likes: I like is the removable water bladder holder, that turns into a daypack/hydration pack when removed. This pack has it all and with it's quality make and materials, I know it will last me for years to come. Great pack and worth the money!

Dislikes: none

Great backpack, maybe slightly too large
Reviewed by Nicole C. - September 30, 2018

Likes: This backpack may be good for long backpacking trips. We purchased to compare with the Gregory Baltoro 65 and decided with the smaller size. 65L was plenty of 3 days with room to spare. The functionality of the backpack is great, like any other Gregory backpacks.

Dislikes: With Gregory it's important to try on to see if you would like the curved lumbar support.

Great multiday pack
Reviewed by Sean M. - May 31, 2018

Likes: Main compartment size and layout in general
Lashing points

Dislikes: So far none

excellent pack for multi-day hikes
Reviewed by RS - May 11, 2018

Likes: ventilation, hip straps, overall balance, easy adjustments, convenient water bottle strap.

Dislikes: weight is considerable, external mesh "shove-it" pocket is poorly designed: placed in the middle of the pack, it is a point of contact with rocks or whatever you lean your pack against. The material it is made of is soft and stretchy and thus, sustained significant damage from just 3 days of hiking. Belt pockets could be just a tad bigger to accommodate the size of IPhone 6
