With astonishing versatility, the Blue River Chest/Lumbar has been a staple in the Fishpond line since our inception. It can be worn as a lumbar, chest pack, sling pack, or mounted onto our Switchback Wading Belt System. Regardless of how you wear it, everything is right at your disposal when you need it, and out of the way when you don’t. You’ll be surprised at how much you can carry in the Blue River pack.
