Note: Using a flexible tape measure or Gregory Fit-O-Matic, measure the length of your torso from the C7 vertebra (at the base of your neck) to the spot on the spine level with the top of the boney hip structure called the iliac crest. Do it two or three times to get an accurate measurment. If you are between frame sizes, always go with the smaller size.

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.
