The rabbit Women's Hydration Trail Tank is a breathable tank designed to work seamlessly with the hydration bra to keep you fueled and comfortable on your outdoor adventure. The racerback design allows you to easily access your hydration bra's pocket, so you can refuel on the move without stopping. Worn on its own, the tank keeps you comfortable all day thanks to super soft EZ1™ PERF materials that keep you dry with its light and breathable design.
