These fleece-lined pants were created after a series of reviews of comfort, details, and silhouette. The fleece is bonded to the entire back for warmth, but the secret to their popularity is that they give you beautiful, slender legs without anyone noticing that they are fleece-lined. This season, they have been redesigned with a center elastic band at the back of the waist for a better fit, and Pocket have been redesigned. They are also available in 18 sizes with a choice of leg lengths, which is great, isn't it?
