Luxe warmth never looked so good. Oakley B1B Mittens are packed with tech specs and stylish details. We started with a stretchy, durable polyester-spandex blend and coated it with our waterproof laminate to keep your hands weather-protected. Next, we added goatskin to the palms for supple flex, internal elastic at the cuff and velcro closures to keep moisture out and mitts in place. All that's left is to head out and enjoy.
