The High Altitude Down Pants are designed purely for attempts on the World's great mountains. Every detail has been crafted to achieve the delicate balance between warmth and weight, critical for any summit attempt.

Hydronaute XT shell fabric is the only choice when it comes to the protection of you and your down products from wind and moisture. Hydronaute XT has been developed specifically to protect and enhance the performance of down sleeping bags and clothing. It makes the best insulation even better.

Hydronaute XT protects down from moisture on the outside, but it's on the inside where Hydronaute XT really proves its worth. Moisture vapour produced by the body can condense in the down of the garment reducing it's ability to loft. With Hydronaute XT, moisture vapour is pulled through the membrane via a molecular chain keeping down drier, maintaining loft and ensuring greater insulation and comfort.

Worn by the Australian Antarctic Division, countless expeditions to the great peaks, and adventurers in the most severe conditions on earth the Mont High Altitude Jacket is a proven garment for survival in extreme weather.
