Arc'teryx Rho LT Mens Crew 2026

Light, comfortable trim-fit base layer for mixed output in cool temperatures.

The base layer crew – the foundation of your system. Made for mixed output activities on cool and cold days, the Rho LT adds warmth, is made with wicking fibres, and is super soft next to the skin. Its Torrent™ microfleece fabric is brushed for thermal performance and comfort, and a Polygiene® treatment provides odour control. The trim fit and crew neckline layer easily, and articulated patterning gives you freedom of movement.
