Comfort starts with your base layer. Built for performance during lower-efficiency activities on cool days, the Rho LT zip-neck adds warmth, wicks away moisture and is soft next to the skin. The Torrent™ fabric is brushed for thermal performance and comfort, and a Polygiene® treatment provides odor control. The fit maximizes fabric performance and facilitates layering, a deep front zipper makes donning and doffing easy, the chest pocket secures your smartphone, and the high collar adds warmth.
