Review: The best of the best undergarment ski wear - Soft, warm, and the right fit for undergarment ski wear!!
Review: Dependable Smartwool Quality - Soft, quality Merino wool that's worth the price. Wouldn't recommend to wear alone as leggings, yet fabric is thick enough to provide true warmth. Really well made with a gusseted crotch and a wide waistband for comfort. At 5'8" I appreciate the generous length. Size chart is accurate. I'm typically a medium but since I'll be wearing these around the house and as pajamas rather than layering, I opted for an overall looser fit in a size large.

### ⭐⭐⭐⭐⭐ I'd give them 10 stars if I could!
*by A***M on January 24, 2026*

These long undies are AMAZING. I live in a very cold climate, and I've bought a lot of base layers over the years -- silk, cotton, poly, tech fabrics -- mostly because they were cheaper. Finally, this year, I decided to bite the bullet and try the expensive stuff (mostly due to the free returns option). These have turned out to be so worth it, and my husband is happy that in our current winter weather -- in double digits below zero -- I'm now willing to go outside, because I'm WARM! Even better, these feel like I'm wearing the snuggliest pajamas. I'm looking forward to more cold days just for the opportunity to wear them. Oh, and I've found that if I machine wash them on gentle and then hang them to dry overnight, I can wear them for multiple days in a row. I haven't had any shrinkage of them yet, either. I'll be watching for sales to try to get another set.
