Thermal leggings of my dreams

These are lightweight, stretchy, and warm but not stuffy. I live in Minnesota and wanted a warm layer to wear under jeans or thin cotton scrubs on days with single digit highs Fahrenheit, but that wouldn't make me hot when indoors. These are perfect. Mild prickliness noted, which wasn't bothersome to me, but I followed another reviewer's suggestion to wash with Eucalan wool wash and they are softer now with only a hint of prickliness.

Love these leggings

The leggings fit perfectly and are super warm! I am happy with the thickness of the material and the moisture wicking properties which make me want to use them several days in a row. They are a little bit itchy at first (not too bad) but once you wash them they start to get softer. I would definitely order a second pair in another color. I would really also like a loose fitting pullover hoodie with a kangaroo pocket made of the same material. I didn't see this type of hoodie on your website but just a friendly suggestion. Thank you so much!

Love these leggings

Warm, soft, comfortable fit, lightweight…I could live in these leggings! I’m impressed with how warm they are! I love how they stay fresh even after multiple days of use. They have become a standard clothing piece for my thru hiking pack. Highly recommend!

Most delicious leggings I've ever owned

Alpaca warmth. Well-designed fit. Lovely color. I now own two pairs of thermal underwear but only ever wear these. So yummy.
