New for 2013! Weighing just 2.4 ounces, the breathable, wind-resistant Salomon Men"s S-Lab Light Jacket is absolutely ideal for any aerobic activity that demands weight be kept to a minimum. Though not truly waterproof, the jacket is water-resistant. Climawind Pro construction delivers excellent protection from the wind while maximizing breathability to keep you from overheating. The full-length zipper makes it easy to take the jacket on and off and also enables you to vent the jacket when necessary. Minimalist elastic cuffs keep sleeves in place. Reflective highlights in the front and back of the jacket provide excellent low-light visibility. Available in your choice of sizes, the Salomon Men"s S-Lab Light Jacket has an active fit that allows it to be worn over t-shirts or lightweight baselayers. When not in use, the jacket packs down as small as your fist.
