What our customers are saying about Altus Alpen pants

Good technical pants

2026/09/14

Miguel

Good technical pants for demanding mountain conditions in the winter season. They look quite well finished, and you can´t ask for more at the price I bought them for (less than €100). I wouldn´t use them for skiing but I do see them as suitable for high mountain trekking in winter. I haven´t tried them on a long trek yet, so I can´t comment on their resistance to rain/snow or their breathability, but the seams look sealed and I find the color very nice. Size M is perfect for 184cm and 75kg, the fit is rather loose but without being too loose. They have sealed seams, two zippered pockets, and an adjustable waistband, and you can still wear another belt on top for better support. They have ventilation openings, although they would be better if they had an inner mesh. The inside of the pants is not unpleasant, but it is more comfortable to wear them with a base layer (ideally merino wool)

While specific material and fit data for comparison isn't available, the feature set of the Altus pants clearly defines their role.

Verdict

The Altus Alpen Pants are a highly specialized piece of equipment for serious winter mountaineers, ski tourers, and ice climbers. Their combination of advanced waterproofing, breathability, and mountain-specific features like the RECCO system and Cordura reinforcements sets them apart from general hiking or insulated pants.
