Men's Arc'teryx Rho SV 1/4 Zip

5875-X000009922

The Rho SV Zip Neck is our warmest, most technical base layer yet—constructed to keep you comfortable without creating bulk. The synthetic, hollow-core fleece is breathable during high-output ascents and descents, while the zip-neck and extended collar provide an option for extra ventilation or additional coverage, depending on what the conditions call for.
