Dynafit Flask

Unless your local trails are equipped with water fountains every mile you’re going to need to bring water on your run to stave off dehydration. The Dynafit Flask shrinks as you sip, so not only does it get more portable as you go, it also minimizes the sloshing you get with regular water bottles. BPA/PVC free and integrates perfectly with Dynafit running packs and belts. It’s the small things folks.
