Lap your goals day and night when you wear your reflective and ultra-hydrating CamelBak Circuit Run Vest. Delivering 20% more water with every drink, a tube trap keeps fluids easily accessible and then tucks right back into place so it's not flapping around while you run. Holding up to 50 ounces of your energizer of choice, you'll barely feel it thanks to 3D Micro Mesh weaved throughout the rest of the vest keeping its total weight at just 5 ounces.
