Polartec Alpha

Polartec Alpha is one of the latest evolutionary steps in synthetic insulation. Based on Polartec’s Thermal Pro High Loft technology platform, it has an open, woven construction which combines warmth with hyper breathability. At the same time it is also extremely compressible and provides warmth without the same level of weight or bulk as traditional insulation fabrics.

Alpha is designed primarily for garments destined to be highly efficient insulation layers for use with a shell in stop-and-go activities where weight and space are limited. When utilised in garments that are worn alone, it delivers exceptional breathability and a quick dry time for a remarkably broad comfort range. Alpha insulation is ideal for fast-paced outdoor activities like backcountry skiing, mountaineering and ice climbing.
