I purchased these for winter mountaineering and have only worn them twice. In the winter mountains, I wore these pants with thermal underwear underneath. They have stretch. I am selling them because I no longer have the opportunity to wear them. I hope someone can make good use of them. *Please only purchase if you understand that these are used items. I will pack them carefully and ship them. These are from the original brand PAINE, sold at Ishii Sports. The concept of the PAINE brand is to identify what mountaineers need and the shortcomings of existing products, and to provide feedback for product development. Because they are made by developers who are always seriously engaged with the mountains from the user's perspective, they are reliable and have been loved for many years.
