Capilene® Air is the most advanced baselayer Patagonia has ever made. It has the greatest range of warmth and comfort of any of their baselayers, insulates even when wet, dries quickly, and resists odors for day after day use. Made from an airy blend of 51% merino wool from New Zealand 49% Capilene® recycled polyester, Capilene® Air feels light and soft on the skin and stretches naturally to move with the body in motion. The soft 18.5-micron-guage-yarns used in Capilene® Air are created with an innovative airblasting technology that dramatically increases the yarn’s loft while reducing weight compared to traditional wool yarn. The seamless 3-D construction eliminates chafe points throughout the entire garment and nearly eliminates wasted material. The bottoms have a brushed, elastic waistband for next-to-skin softness, a double layered crotch for support and a gender-specific box-stitch texture to trap warmth and allow airflow.
