    Rated 5 out of 5 by from Love the fabric! I bought these leggings for walking the dog in winter. These appear to be perfect. They stretch nicely but feel nice against the skin. I am 5’ 1” and the 7/8 length works perfectly.

    Rated 5 out of 5 by from LOVE So far I love these leggings! I have yet to try them out for running but they are super comfortable and not too thick. They have a good balance of stretch/compression and are true to size.

    Rated 4 out of 5 by from Pretty Good We just had our first COLD morning in Colorado! It was 26 degrees at 5:30 a.m. I was pretty warm for about 25 minutes into the run and then my butt started to get really COLD! I think these would be great paired with something to cover my butt. The material is really nice, they are very soft inside and stayed in place for the most part while running. I did have to pull them up a few times. I will continue to wear these anytime it is between 26-38 degrees. I am really considering buying the matching top!

    Rated 2 out of 5 by from Not sure these are right.. I bought these for outdoor hiking/activity in cooler weather. I'm trying to figure out if I received the correct size (I'm in the US so size conversion...) But if they are correct then they run very large and loose. I would not wear them for running they have no compression. The stripe is also made of velvet which I could not tell online - so maybe just better for non athletic endeavors

    Rated 4 out of 5 by from So cozy I bought these leggings for winter running but then got injured and couldn't run. Instead I just lived in these leggings all winter. They are the coziest. The fabric does seem to pill a bit after a while, and I'm always worried about snagging them, otherwise I love them!

    Rated 5 out of 5 by from So much love for these leggings! <3 I adore the look of these leggings and when I found out they were fuzzy inside my heart jumped for joy. I've worn them for several runs on freezing cold days and they've been supportive, cozy, and feel so stylish. The velvet stripe on the side is just gorgeous.
