- ErgoFit - The human body is complex with intricate detail and function. The same attention to detail is present in the design of our packs to enable precise movement, contact, and weight distribution which ensures that there is never any inhibition to the biomechanics of the human body.
- UltrAcool Light Mesh: The UltrAcool Light Mesh on the back panel eliminates any discomfort when fully loaded. Accessing the back compartment is made easier by a soft foam flare which extends up, guiding your hands into position. The back panel also houses a sweat proof pocket.
