Oakley Women's Drift O-Puff Jacket The Drift O-Puff Jacket is your ultimate, ultra-warm layer for peak-bagging, cold descents, and all the snowy fun you can have. We made this piece with 100% recycled material, and filled it with 3M Thinsulate Eco Down: a soft, thin, and lightweight fill with incredible warmth – even when temps get frosty. Stretch hems at the cuffs and binding help keep out snow, while Hydrofree DWR treatment repels water from the fabric to keep you cozy and dry. Best of all? An inner pocket doubles as a stuff sack for quick, easy packing when it’s time to skin up or cool down.
