Arc'teryx Rho AR Zip-Neck Top - Women's for Sale, Reviews, Deals and Guides

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.
