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.
I love the FP Field series. This is the only bag from the series that I actually use on the river. Works great as a sling or as a lumbar pack. I use it for quick, 2-3 hour trips. Plenty of space for a few fly boxes, a clif bar, water bottle, and a few extra tippets. Looks great, too. I've also used it as a daypack while traveling, and it has enough space for maps, guide book, extra layer, a few snacks, and backup phone battery.
