"Extremely comfortable and excellent fit, this will be a go to layering piece for this fall and winter. I am a size 4 or IT40 in pants and small fits great."

"Really great as leggings and base layer. Im 38 hips, 30 waist 30 inseam and I got a small black. These are leggings and fit really well with the waist design and length but they also double as a base layer. They are thick enough to wear alone. They arent as soft and stretchy as the woolies tech pro but they are sturdier fabric and comfy. They work on the bike over bike shorts with softshell pants when its really cold."

"Soft and comfortable. Perfect at base layer under my ski pants. And then as lounge wear with a fun shirt or dress. Wearing on repeat right now"

"I’ve been wearing these every night as sleep pants for two weeks. Very comfy. The sizing tool recommended a L but I purchased an XL because I have larger thighs and calves and it fits well. The only reason I rate this as four stars is because I would appreciate pockets. I understand this is a base layer but I feel like there must be way to incorporate pockets or a pocket while still maintaining the slim function of a base layer."

"These are now my daily base layer, perfect for the Mt Shasta winter temperatures. They are not too thin and not too thick so I feel the warmth without the bulk. I will buy more when on sale! The medium works well for me and I am 5’5” & 125 lbs."

"I opened the package and immediately was a bit worried because they looked a bit thin. I put them on and the fit was great. I have worn them multiple days hiking through the snow and snow shoeing as a base layer and have absolutely loved them. Temp was 14° today and I was toasty warm, but did not feel like I had bulky leggings on. They are super warm. Ibex is my new favorite."
