The less layers the better when nature has the heat turned way upour exact thought when dreaming up our Backcountry Wasatch Adventure Hydration Bra. The compressive stretch gives us the support we need, while the soft, wicking fabric feels cooling against our skin. We load the front mesh pockets and side envelope pockets with energy-boosting gels and stuff an emergency rain layer in the back pocket. As we stride singletrack, the pockets' stretch material minimizes bounce, the zipper's internal flap and garage reduce friction, and the convenience has us feeling light.
