Insulated overtrousers that provide critical extra warmth for super alpine climbing ski-mountaineering, winter camping and expeditions.

We've used these on cold weather expeditions in Norway, Sweden, Greenland and the Poles. Taking stiff salopetes off at the end of a long day, and putting on these super soft and comfy pants is a luxury and moral booster.

Full length zips means that toilet breaks are simpler, and zips are also useful for venting and dumping heat, should you need it.

With a tiny pack size the Compressor Pant is a crucial extra layer for alpinists and skiers. Full length side zips make them easy to put on even whilst on skis and the POLARLOFT® insulation keeps working in the face of hostile conditions. Essential kit for summit pushes or winter camps.
