Your hand will never have been more comfortable carrying a water bottle than when you use the Nathan VaporDraw Water Bottle. The contoured, ergonomic design of this bottle will allow your hand to get the best grip on the bottle and not alter your running form. A mesh hand strap will further secure this hydration system to your hand which can be adjusted to suit your needs. The zippered side pocket allows you to store small essentials such as keys, snacks, or cash. Reflective detailing on the outside of this carry system will give you a bit of added safety when you are working out during low light conditions. For a water bottle carrier that will contour to your hands and be comfortable for your longer runs, this hydration system will outperform them all.
