【Hydration On-The-Go】Stay hydrated without interrupting your pace with the Walroysu Running Hydration Vest. Equipped with a 500ml soft flask that is 100% BPA and PVC-free you only need to gently press the water bottle to replenish water. The bottle shrinks as you drink and combined with a drawstring tightening system it minimizes sloshing bouncing and rattling.
