Description
Made for high exertion in cold settings, T3 base layers deliver warmth without inhibiting your mobility. When your're chugging up steep switchbacks, the lightweight Polartec Power Grid® offers excellent moisture management – the inner side rapidly wicks moisture away from the body, while the outer yarns disperse dampness for quick evaporation. On the inside, a voided grid construction traps air for greater warmth and increased breathability.
- Polygiene® silver ion treatment provides odour control.
- Gusseted crotch.
- Waistband logo is heat transferred, not sewn in, for increased comfort.
- Daily deal products are for a limited time only, while quantities last.
