Have not worn these yet - my review is based on trying on the leggings. The fit and fabric are excellent. Fabric is soft and not as itchy as some wool base layer pieces and there is a good amount of stretch and recovery. They look to be well made - I especially like the waist band construction which is more like a pair of work out leggings than the basic elastic waist other competitors use. I would definitely recommend - and will follow up after wearing!
I’m 5’5” weighing 135 pounds. I’m pear shaped. My hips are 40 inches and my waist is 29. The L size fits beautifully. I tried them in and just kept them on for the night. So comfy!!
I got these to use under my waders for fall steelhead fishing in the PNW. It’s been getting down to the high 30s low 40s just before sunrise and I felt pretty comfortable getting in the water with these. I tent to run cold so these are warm for a base layer.
I use these bottoms as a base layer for winter hiking and kayaking. They are very comfortable and warm. I usually do not like wool next to my skin, but these are very soft and not bulky. I will be using them on a kayaking trip in Greenland in August.
Merino but soft! I just got these and wanted to try them out, so I wore them on a day that was not quite cold enough for two layers. They breathe quite well so I was super comfortable the whole time we were skiing. Soft and comfy with good seams that didn't bug me. A big win!
These are very comfortable and they don’t slip or sag down. These kept me warm in the Utah backcountry when winter backpacking!
