If it's not enough that Evoc set the pack and bike-transport world ablaze with its revolutionary German-engineered, spine-saving FR Protector series of hydration packs, they had to go and up the ante with the FR Enduro Blackline Protector Hydration Pack. So named for its distinct and sleek styling, the Blackline is hardly just a styling statement -- it's built to last. Like many other Evoc packs, this one is made primarily of an ultra-tough and water-resistant blend of PU-coated ripstop nylons, tarpaulin, and neoprene. The result is an amazingly light but bombproof pack, and that's only the beginning. For breathability, the Blackline uses 3D Air Mesh along its paneled backing, and even the elastic Airo Flex waistband is micro-permeated to bring in the breeze. For all your gear, there are stretchy side pockets, and a swing-open tool compartment, along with the large main storage area and multiple external straps to carry your helmet, pads, or other gear. The pack doesn't include a hydration bladder, but because this pack is all about keeping you going for long days on the trail, it's ready to accept one up to three liters in size. No description of an Evoc Protector pack would be complete without highlighting the technology that gives it its namesake. All Protector packs are CE-certified with Evoc's LiteShield back protector, a system featuring a super-light pad with an EPS core and foam damping layers that reduce shock to the spine by up to 95% in the event of an accident. Completely replaceable in the event of being damaged, the ISP (Integrated Spine Protection) plate and its associated materials only add approximately 150 grams to each pack into which the system is integrated, making the decision just that much easier for riders who ride hard and push their limits.
