Say hello to your cold-weather hero: the Dog-Walker Fleece Legging. With a buttery fleece lining on the inside and a smooth, cotton-like finish on the outside, these best-selling leggings are all about comfort. We designed our Dog-Walker series for cold mornings, you guessed it, walking our dogs. That means side pockets that fit a phone and keys were a no-brainer, as well as a longer inseam to keep our ankles warm.
