Rho AR Zip-Neck Top

Rho, the 17th letter of the Greek alphabet, carries many meanings. You might not find it on wiki, but in this instance, the Arc'teryx Rho AR Zip-Neck Top signifies a midweight thermal baselayer. Polartec Power Stretch fabric offers warmth without much weight, and it wicks moisture to keep your temperature constant. A trim fit prevents sweat from accumulating on your skin, thus reducing the probability of sweat-induced shivers. Unzip the neck zipper when your core temperature climbs. Wear the Rho on its own or over a silkweight shirt for high-intensity aerobic activity in cold weather, or layer the Rho under jackets and shells for less intense endeavors in single-digit temps.
