Hybrid Tights.

The women's Phase AR Bottom is a soft and durable base layer tight, created for high-intensity activities like hiking and skiing. This tight utilizes Phasic™ AR fabrics, which are made from different polyester structures on the interior and face to disperse moisture. It also has strategically mapped lighter paneling to reduce bulk and improve thermal efficiency. Arc'teryx engineered this stylishly streamlined tight in a next-to-skin fit, which provides insulation and an excellent stretch. This tight is an ideal base layer and can even be worn as an insulating outer during morning runs.
