Product details:

This technical top is perfect for highly active snowy days. The body features merino wool fabric with a touch of LYCRA for stretch. The underarm panels feature lightweight eyelet merino mesh that actively controls temperature during high-output pursuits, and in the higher-wear areas merino and Polyester waffle jersey add toughness to the fabric. Offset, flat lock seams prevent chafing when you're wearing a pack, and the droptail hem offers additional coverage.
