Arc'teryx Phase SV Zip-Neck Top - Men's

The stop-and-go aerobic activity of ski touring, snowshoeing, mountaineering, and climbing can all lead to a bit of a chill if your base layer isn't up to the task. So Arc'teryx crafted the Men's Phasic SV Zip Neck Top for efficient insulation and wicking, so you can stay comfortably dry all day long. The top's soft, fuzzy interior warms you and draws perspiration away quickly, and its smooth outer face encourages quick evaporation. The Phase SV Top glides easily under your other layers, and a deep zip neckline lets you boost ventilation when you're breaking trail.
