Why call 'em Cloud 10? Because they're so soft, lofty and cozy, naming them "cloud nine" wouldn't do these mittens justice. Our exclusive lightweight Cloud 10 polyester fleece is plush and stretchy – warms without bulk, keeps your fingers nimble. And it's knit with 7% spandex for a close-to-the-hand fit that keeps chilly drafts out. Even better? Inside there's a 100% polyester berber fleece lining that warms while surrounding your paws in amazing against-the-skin soft. Welcome to brrr-free bliss.
