A new baselayer for Winter 2010, the Women's Integral Long Sleeve Crew from Mountain Hardwear is a Merino wool and recycled polyester jersey fabric that wicks moisture well and provides optimum warmth and performance. The Micro Climate Zoning utilizes wicked taper mesh to increase breathability and the flat-lock seams are rotated away from abrasion areas for comfort. An anti-microbial finish helps to control odor.
