A Oiselle woman is always ready to conquer the coldest days, because she's stocked up on styles that go the distance. When the mercury dips, a regular beanie won't cut it–you need to get technical. That's where the Power Move Beanie comes in. Made from Polartec® PowerStretch knit, it's got a soft and smooth exterior and a fleecy interior that'll keep you pleasantly warm, but not overheated, as the miles tick by. Our favorite part? There's a specially designed flap in the back for your ponytail to peek through.
