The Topo X is a collaboration between the guys over at Howler Bros. and Topo Designs. If you have moved on from the old school fishing vest and prefer hip packs this one won’t disappoint. The Topo X works as both a hip pack and a shoulder bag. The outer is made of a Cordura fabric and the bottom is made from a military spec vinyl to keep your gear dry when your wading deep. Made in the U.S.A.
