Arc'teryx Men's Phase SV Zip Neck

Arc'teryx warmest weight base layer zip neck in the Phase family is appropriate for cooler temperatures and high-output activities. Composite construction of Phasic™ SV and Phasic™ AR fabrics in addition to the textile’s construction and next-to-skin fit eliminates excess bulk and rapidly transfers moisture for efficient evaporation. Ideal for cold days in the alpine, this super-wicking base layer has mid-level insulation to keep you warm and dry, and a zip neck allows for faster venting. Engineered for superior moisture management and rapid dry-times during stop-and-go activities, this form-fitting top keeps the user drier and more comfortable. Encapsulated silver-ion fibres provide durable and long-lasting odour control.
