Ascents generate more body heat than any other action on the bike. And if your day is going to be comprised of massive elevation gains, your best bet to keep cool is the Pearl Izumi Elite LTD Climbers Jersey. Why' Well, instead of using Izumi's Transfer or P. R. O. fabrics for the construction, the Climbers Jersey is made entirely from its Direct Vent mesh. This means that your core is going to enjoy the pinnacle of ventilation, breathability, and moisture wicking during your painfully long exertions on the mountain. As a result, you'll remain cooler and dryer than with standard fabric constructions. And, even if you manage to accumulate excess body heat, a full length zipper allows you to perform on the fly heat dumps when necessary. And while the Climbers jersey has temperature related comfort dialed in, Izumi also designed its Direct Vent mesh to be comfortable against the skin. It has a soft to the touch feel against the skin, and it also features a four way stretch construction. So, you'll experience a complete freedom of movement while you're moving in and out of the saddle on climbs. At the back of the Elite LTD Climbers jersey is an elasticized gripper that keeps the jersey in place. Three back pockets reside here as well, and there's a hidden, sweat proof pocket for housing of your electronics. The Pearl Izumi Elite LTD Climbers Jersey is available in five sizes from Small to XX Large and in the colors Centerline Black and Centerline Cherry Tomato.
