This Evoc MTB pack is quite literally packed full of features, but what truly sets it apart is the integrated Airshield back protector. This certified protector absorbs some of the shock of over-the-bars tumbles, but doesn't sacrifice your riding performance thanks to its ergonomic shape, comfortable flex, and 360-degree ventilation that helps you stay cool. Carry all your water, tools, and snacks with a little extra peace of mind.
