This pack has been around awhile and should be for a few reasons... The Blue River Chest/Lumbar pack is a great alternative to a vest, it can be worn as a lumbar, chest or sling pack. Regardless of how you wear it, everything you need on the water is right at your disposal, and out of the way when you don't. You'll be surprised at how much you can carry in it. Its got a main storage compartment with three interior pockets, zip-down fly bench with replaceable foam, tabs and elastic loops for accessory attachment, access points for tools and hemostat.
