Functional, versatile and durable are just a few words that describe the Fulcrum, but here at Kifaru we just like to call it a kick ass Extended Mission Pack! The base design for the Fulcrum is very simple; deliver a pack with the ability to expand to 7,800+ ci, but also transform into a sleek and functional daypack when needed. We were able to accomplish this by adding a full length center zipper to the main bag, and also add 900 ci wings to each side. The options of the Fulcrum allow for quick access, mass expansion and/or compression and the versatility that is rivaled by no other large pack on the market today.
