Arc'teryx Bora AR 63 Review
The "GridLock" system is Arc'teryx's adjustment system which is featured on the Bora as well as several other of their packs. What makes it fairly unique is that packs constructed with this feature can have their shoulder straps adjusted both vertically and horizontally to best fit their wearer. Despite looking pretty simple this is a BOMBER design and we never experienced the shoulder strap becoming prematurely undone.
