Manufacturer’s description:

Made for high exertion in cold settings, T3 base layers deliver warmth without inhibiting your mobility. When you’re chugging up steep switchbacks, the lightweight Polartec Power Dry 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.
Full coverage hood with chin guard.
Long sleeves with thumbholes to prevent slippage.
Neck logo is heat transferred, not sewn in, for increased comfort.
1/2 length zipper for venting.
