Macpac Women's Prothermal Fleece Long Johns

Prothermals are our highest performing synthetic base layers. These thermal leggings are made with Polartec® Power Grid™ fleece for superior breathability, lightweight warmth, and compressibility.

This fabric's internal grid pattern wicks moisture to keep you comfortable for longer. Polygiene StayFresh™ technology uses silver chloride sourced naturally from water and soil. This technology prevents the growth of odour-causing bacteria, keeping unpleasant smells at bay. A touch of elastane ensures free movement.

Ideal for climbs and active pursuits in cold weather.

Polartec® Power Grid™ is made with 25% post-consumer recycled content.

bluesign® approved means this fabric has been manufactured with the responsible use of resources.
