When you've finished cutting weight from every other part of your equipment list, there's one place left to turn: your backpack. Gregory's Z55 is the second-largest member of the company's lighter-weight "Z" family of backpacks, dropping nearly a pound and a half from the weight of its more deluxe counterpart, the Baltoro 65. The Z55 features a large front panel zipper that allows easy access to all of the packs' contents, as well as a large and well-cushioned lumbar pad that helps transfer the weight of the load to your hips. Gregory's Jetstream suspension system opens up a little bit more airspace behind your back compared to the Response and Kinetic suspension systems found on other Gregory packs, which helps to keep you cooler on hot summer trips.
