Sure, you'd like to head out for a nice relaxing trail run with nothing but some water and your own two feet, but there's always the chance you'll need a shell, a call for help, or a mid-run snack. When your running belt just doesn't pack enough, tack on the Ultimate Direction Adventure Pocket for added storage and reassurance on the trail. Compatible with any Ultimate Direction Signature Series belt or the Everyday Carry water bottle, this storage pocket is made from a breathable mesh fabric with a 4-way stretch to help hold your valuables. The front pocket is iPhone 7 compatible, so you can avoid struggling to make your phone fit.
