Our most versatile baselayer with the greatest comfort range is made with Polartec® Power Grid™ fabric with Polygiene® permanent odor control and Fair Trade Certified™ sewing.The Sierra’s superb Evolution traverse combines a chilled, pre-dawn start, high-altitude temperatures and sometimes-frigid shade with a non-stop, all-day pace. Designed to manage the extremes of high-output exertion, our Capilene® Midweight fabric hits the sweet spot of weight, breathability and wicking. Worn alone or under layers, it keeps you dry and comfortable during high-exertion activities in cool-to-cold weather. Constructed with Polartec® Power Grid™ fabric, it has a smooth face for easy layering and a brushed-back grid that aids in wicking as well as warmth.
