A staple for alpine climbers grappling with freezing temperatures, this lightweight yet technical hoody has also gained a loyal following among travelers facing a day of variable conditions. Capilene(R) 4 is the warmest and most breathable baselayer in the Capilene family, perfect to support your pursuit of the unknown. It has a soft, stretchy feel, with a smooth knit face that glides beneath layers and a brushed fleece interior to warm your core, wick moisture and rest smoothly against your skin. Hidden thumb loops ensure wrist coverage when you?re climbing and an anatomically shaped hood with a tall collar blocks the wind and increases coverage and warmth. An elongated front zipper quickly vents heat, raglan shoulder seams allow chafe-free movement, a chest pocket stows your energy bar and a drop-tail hem stays put under a harness. Made of 3.8-oz Polartec(R) Power Dry(R) High Efficiency fabric with Polygiene(R) permanent odor control. Fabric is bluesign(R) approved. Beginning with our Spring 2015 styles, we've improved our women?s fit: There?s a slight increase at the waist for shaping and to ensure the fit is truer to size. All other measurements, such as chest and hip, remain the same. Please refer to our new, updated Women's Size Chart and Fit Descriptions for details. Note: this change applies to full-price Spring 2015 styles, not to past-season or on-sale items.
