I love these sweatpants

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!

Women's Alpaca Wool Sweatpants

Great quality Sweatpants. Compared with others on the web, they look much nicer and are much more comfortable. Wool is the best material for sweatpants! Good for your body and health! Love them! Thank you!

Hi Diana,
Thank you for your kind words! We're so happy to hear that you love the quality and comfort of our sweatpants. We couldn’t agree more—wool truly is the best! We appreciate your support and hope you continue to enjoy them.

Warm and cozy but just a tad itchy

Don’t get me wrong these joggers are great! Very high quality. Nice and thick fabric. Very warm and cozy but just a tad itchy on the skin. The itchiness did lessen as I wore them and got used to it and I think after a few washes it will go away completely. I would say they run true to size but a tad on the larger side as well. I’m 5’6” and 140lbs and I ordered a size small and they were fitted like I prefer but not too small at all. If you want baggy just size up. Highly recommend!

Hi Jess,

We’re so happy to hear that you love the quality and coziness of the joggers! It’s great to know that they’re keeping you warm and comfy. The fabric does tend to soften with wear and washes, so we hope they’ll feel even better over time!

Really appreciate you sharing your experience and sizing insights—it’s super helpful for others. Thanks again for the recommendation!

Good Quality Alpaca, Poor Attention to Detail

My sweatpants arrived with a hole in the pocket. I sent multiple emails to customer service and never received any reply. Given the price, I was hoping for better attention to detail and quality control. The alpaca itself is warm and very cozy.
