If you enjoy shorter rides or races, Evoc has designed its FR Enduro Protector Hydration Pack specifically for a women's shorter torso and narrower shoulders. It also features built in spine protection for downhill runs and big drops. In general, women have shorter torsos and narrower shoulders than men. And while you can make a unisex pack to fit, when back protection is added, you want the plate to fit securely to your spine. The plate included in the Enduro pack is a series of polyurethane and EPS foam layers that are segmented to conform to your individual shape. To secure the women's specific pack in place, the Evoc pack features adjustable shoulder and sternum straps and a padded hip belt. The Evoc Enduro pack is slightly more compact than the FR Trail version. It holds just under 1,000 cubic inches of gear divided between a main compartment and a fold out tool flap. The flap contains a series of organizers that separate your tubes, gels, keys, phone, and any other small accessories. Straps in the bottom secure your pads, and the far back panel releases to accommodate a helmet for lift serviced rides. The Evoc FR Enduro Hydration Pack Women's is available in the colors Mud and Navy. It comes in sizes Small and Mediumlarge and is fitted by height. Please see the size chart for specific height and torso measurements.
