    the stiches were incomplete. the oddore of the pack was stincky - like sierra put fish in the bag before. I have got poor quality , second handed like bag . the internal coating of the nylon was takky. deuter bags look not less of a quality. that is sad. dissapointed from the bag finish inside and outside . it seems that deuter packs are better build beside the only good thing wich is the suspention. over all that is not the quality product i had expected from gregory . gregory no more . sierra trading no more. lowe or deauter yes yes.

  • “I need help measuring so that I order the correct size. Do you measure torso length from the shoulder to the top of the buttocks or under the buttocks? This seems pretty small even in the large size. I am only 5'6" and have a short torso... but that depends on the points of measurement I suppose.”

About Gregory

After designing his first backpack as a Boy Scout at the age of 14, Wayne Gregory dedicated his career to making outstanding gear, a mission that eventually led him to create Gregory Mountain Products in 1977. From the beginning, Gregory backpacks have been engineered using a combination of field research and customer feedback in order to enhance durability, fit and function. The brand has pioneered many industry firsts, such as multiple pack sizes with different frame, harness and waist belt dimensions. They also developed the first waist belt system that offered a variety of hip angles. Not surprisingly, Gregory backpacks have been praised in a wide range of publications, from Backpacker magazine to National Geographic Adventure.
