A winter baselayer should be warm, but still breathable. A high zipped neck and long hem are also essential. In this group test we've trialled winter weight baselayers from a number of leading brands.
Engineered with Phasic technology, the Phase line is designed to wick perspiration, dry super quickly and resist odour thanks to encapsulated anti-bacterial silver ions. What's more, they offer the added bonus of inter-woven UV SPF 50 protection and are of course completely anti-chafe.
Phasic is an innovative performance-based technology which rapidly transports perspiration during an active, athletic phase, disperses moisture across the garment in the recovery phase, and dries out quickly while at rest. Coming in three weights of fabric, the Phase collection has something for every type of athlete, providing a warm foundation under a mid-layer, or acting as a primary layer on a warmer winter day.
As you can expect from Arc'teryx all products, the Phase Line offers incredible fit and comfort in a palette of stunning colourways. So whatever sport you're into once you try the new Phasic technology, there will be no turning back.
