I’ve worn these bottoms as my go-to, everyday baselayer this winter and am very happy with the warmth, durability and range of uses. And yes they work as my around the house pants too :) The bottoms have lots of stretch, and after days (I’ve worn these skiing/ski touring/winter camping for up to 5 days in a row) of wear they return to their original shape once washed (good results with cold delicate wash and hang dry). I was afraid they would be too warm, but they are very light for a waffle fabric. After about 10 washes they still look good with no pilling. I would recommend this product to all merino fans.
