Gregory Discontinued The Z25 November 2016
The Gregory Z25 stood out for its innovative back panel design, making it the most ventilated pack we tested. However, the pack has less organizational options than a pack like the REI Trail 25, but it does have some convenient hiking specific features, like trekking pole attachments. The unique back panel pushes the weight off of the back, and carries weight differently than most of the others we tested. The Osprey Talon 22 and the Marmot Kompressor Verve 26 have similarly designed back panels while keeping the load close to your back, which means they are both a little less breathable, but also remain more flexible and more comfortable for carrying heavier loads. If you're looking for a pack that holds weight well with a narrow profile try the frameless Deuter Speed Lite 20.
