The Bivy 45 is the largest pack in the Sitka pack line. Three access points to the pack’s main compartment (top, bottom, and side), give the user quick access to all his/her gear. An adjustable blaze orange gear shelf can be deployed from the bottom partition and employed to lash additional cargo to the pack’s exterior. A quick-release gun/ bow cable system, removable pack lid, quick detach rain fly, and designated spotting scope pocket are only a few of the pack’s many features.
