Prothermals are our highest performing synthetic base layers. This thermal top is made with Polartec® Power Grid™ fleece for superior breathability, lightweight warmth, and compressibility.
The fabric's internal grid pattern wicks moisture to keep you comfortable for longer. Polygiene StayFresh™ technology prevents the growth of odour-causing bacteria, and a touch of elastane ensures free movement.
Ideal for climbs and active pursuits in cold weather, and as a mid layer in warmer conditions.
Polartec® Power Grid™ is made with 25% post-consumer recycled content. Polygiene StayFresh™ technology uses silver chloride sourced naturally from water and soil.
bluesign® approved means this fabric has been manufactured with the responsible use of resources.
