The Unbound 40 lacks the airflow of some other packs, and CleverHiker noticed accumulated back sweat during use. The Unbound 40 uses a slick, non-abrasive back sheet that moves across the body with little friction, according to CleverHiker. CleverHiker found the Unbound 40 stable and balanced under loads reaching 40 pounds, with its simple frame transferring weight effectively.
The Unbound 40’s hipbelt and side pockets are roomy and easy to access, while its front mesh pocket offers two access points. A lower opening in the Unbound 40’s front pocket helps retrieve items settled below and provides a designated space for small tools.
