Men's Merino Base Layers: Optimal Thermal Regulation

Cool on the way up, comfortable on the way down. Arc'teryx men's base layers bring the warmth without the sweat, featuring winter favourites like the Rho Merino Wool collection. Engineered for rigorous alpine ascents, ski tours, and cold-weather hiking, these technical layers deliver exceptional temperature control and moisture management directly against your skin.

Key Performance Features

  • Moisture & Thermal Control: Advanced merino wool and technical synthetic blends actively wick perspiration while locking in core body heat during high-output winter activities.
  • Natural Odor Resistance: Premium merino fibers provide built-in anti-odor performance, ensuring long-lasting freshness across multi-day backcountry trips.
  • Ergonomic Mobility: Articulated tailoring and next-to-skin fits sit seamlessly beneath hardshell jackets and insulating midlayers without restricting movement.
