Reposhing this item I purchased from @kschip113. These are a fleece legging, not heavy but have a texture that is really nice. I wanted more of a sweatpants and these are leggings. They fit snug like all Lulu lemon leggings do, so a size 6 is a snug fit. If you are a size 4 they will fit a tad looser. I bought these new and have only wore them once due to weight gain. The material is not the flat nylon so look at pictures. Questions? Leave a comment below!
