Randonee racers who prefer a two piece racing suit to the crack crawling onesie will appreciate the fit of the La Sportiva Men's Syborg Racing Jacket. The Syborg delivers both the mobility and breathability you need to flash the ascent, along with the warmth needed to charge on the descent. The jacket's stretch polyester fabric features flatlock seams for a smooth and comfortable fit, and it is equipped with a 34 length center front zipper for rapid venting once you start to heat up. A grip of pockets along the front, back, and inside of the jacket house everything you need for race day. Reinforced shoulders help to eliminate irritation when you're wearing a pack and reduce the chance of tearing when you shoulder your skis during the final push to the summit.
