Arc'teryx Rho LT Zip Neck Top Men's

Conquer changing conditions and fluctuating exertion levels with the Arc'teryx Rho LT Zip Neck Top, the versatile base layer that adapts as quickly as you do. The lightweight Torrent™ stretch microfleece features advanced wicking technology that pulls sweat away from your skin while the deep front zipper offers instant ventilation during those heart-pumping ascents. Whether you're traversing ridge lines or setting up camp in cool mountain air, the articulated patterning moves with your body, eliminating restriction when reaching for that next climbing hold or adjusting your pack.

What truly sets the Rho LT apart is its Silvadur™ antimicrobial treatment, keeping odors at bay during multi-day adventures when laundry isn't an option. The fitted design creates the perfect foundation for your cool-weather layering system, while the minimalist Merrow stitch construction eliminates bulk and chafing—even under a fully loaded backpack. At just 225g (medium), this technical base layer delivers exceptional warmth-to-weight performance for fall hikes, winter ski tours, and everything in between, proving that the best adventures start with what's next to your skin.
