The comfortable and functional Katmai 65 from Gregory is specially built for longer adventures. Featuring an innovative back and shoulder straps made of mesh, the air will be able to circulate through at all times. In addition, the backpack is equipped with a snug carrying system to ensure it remains firm on your back, yet it allows lots of freedom of movement.

In addition to the main compartment and the sleeping bag compartment, it has numerous small pockets, such as the pockets on the hip belt that you can use to stow away your camera. Plus, the backpack is compatible with most commercially available hydration systems, and you can stow away your water bottle on the hip belt’s bottle holder.
