This 3-pack features our newest compression straps with locking buckles to keep your equipment secure. The adjustable female sides allow you to move the straps easily along the pack and the frame loops. To achieve your preferred level of tension, pull the straps; the locking mechanism will activate, preventing the straps from slipping. Press on the locking mechanism to disengage it and loosen the straps. Each strap can be extended to a maximum length of 32 inches.
