I absolutely love these sweat pants. They fit true to size are very warm and cozy. I’d love to have another pair!!
J
I love that these sweatpants have some true weight to them when holding them, but feel so light when on. They are so comfortable and I’ve been loving them this winter!!! They’re slim enough to wear under some of my dresses for some serious warmth.
M
These aren't quite nice enough to wear to work but they look good enough to wear everywhere else. They are slim cut sweatpants so they look neater and more put together than traditional sweatpants. Beyond looks they feel amazing, comfortable and warm, I do always run cold so I love these but if you run warm you might want to consider lighter weight pants for everyday wear. I wore leggings under these and was comfortable outside in below 0 temps. They feel very sturdy and durable but I haven't had them long enough to personally evaluate.

I love these sweatpants and their quality! Soft, comfortable and warm. The waist band is substantial and hits at the perfect location above my belly button which I find most comfortable. Nice to have pockets as well. I appreciate that they are 100% Alpaca wool. I also have the leggings which as a tighter fit, so its nice to have something a little more relaxed, yet not baggy. I am practically living in them during our cold Wisconsin winter months.
J
so glad that I bought them. I also have the mid-weight tights in the same size which are very snug fitting, and these sweatpants are a little more relaxed and comfortable in fit all over. Still flattering but are not baggy. I am 5'4" ~129lb and the smalls are slightly long but it's not a big deal. Enjoying the front pockets. Waist band is comfortable and hits about an inch below my belly button. Love the fabric weight and feel. Substantial and cozy. I have been wearing them daily. Easy to wash in sink and line dry. I regret waiting as long as I did to purchase them :) Love your products!
