iXS Carve Zero Insulated JacketMade from a waterproof and breathable material, and featuring an insulated body, the iXS Carve Zero Insulated Jacket is a top pick for mountain biking in cold, wet weather. The Carve Zero Insulated Jacket is a feature-packet all-weather mountain biking jacket that gets you comfortably on the trails when storm clouds break and temperatures drop. Starting with the outer, this offers a waterproof rating of 10,000mm, keeping out the rain for prolonged periods. Laminated and taped seams also prevent water from seeping inside. An adjustable hood and waist also let you really seal out the rain during the heaviest of downpours. While water is kept out, the Carve is also equally adept at ensuring sweat doesn't hang around inside either. A 20K breathability rating means that as you generate sweat during riding, it has an easy escape route to the outside, leaving you drier and more comfortable on the inside. And if you do need some fresh air to circulate inside, ventilation zippers keep you in control of heat regulation.When it comes to cold weather, the synthetic insulation to the body keeps plunging temperatures at bay, retaining heat generated from riding. The sleeves meanwhile are partially insulated, balancing mobility with warmth. When you're navigating rough terrain, the X-Stretch fabric also ensures you're not hindered as you throw your bike around. Features:Materials: 94% Polyester, 6% ElastaneX-Stretch - multi-directional stretch (4-Way) fabricInsulated lining (synthetic filling) and 3/4 insulated sleeves for optimized sports applicationWaterproof & breathable (WP 10K / MVP 20K)Laminated & taped seamsReflective printAdjustable hood & waistWaterproof YKK zippersVentilation zippersReinforced hood brimSeparate stuff sackBuy iXS Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
