What Our Gearhead(R) Experts Are Saying:"I wore the Gravity 4. 0 Jersey through a scorching day at the bike park and could actually feel the difference on the chairlift. It dried out almost instantly after every sweaty lap, and the fit worked fine over my chest protector."The lift ticket scans and the first lap of the day starts hot, dust already kicking up off the berms before the chairlift even slows down. This is where the Leatt Gravity 4. 0 Jersey earns its place, the IceYarn fabric pulling heat away from the skin almost as fast as it builds. Spun from coffee grounds, it sounds like a gimmick until the third lap in, when everyone else is soaked through and this jersey has already dried. The regular fit sits easy over a chest protector without feeling bulky, and the collar tucks in cleanly under a neck brace for anyone riding with one. Laser cut vents move air on the climb back to the chairlift, and a quick swipe of the goggle wiper clears the dust before the next drop. By the last lap of the day, it still feels as fresh as the first.
