City Threads super-soft fleece stretch leggings are great to keep warm for the fall and winter! Our locally-knit, top-quality fleece is soft and smooth on the outside, and cozy and fuzzy on the inside. Many other warmer leggings are made with mostly synthetic fabrics, but these leggings are 96% cotton, which is more eco-friendly, and has better breathability, and just 4% spandex for stretch. Our extensive fit testing ensures that they will provide maximum comfort and style. The fleece is not too thin, but not too thick - going from inside to outside on a cold day, they will not be too warm inside. Treat your kids and try them out!
