Our warmest, waterproof Expedition collection uses 600 fill-power down to give you uncompromising warmth all winter long. The shell is waterproof and seam-sealed (in other words, WINTER-proof). And it has all the bells and whistles you need for a day in the cold, including plush Sherpa fleece lining in the hood, chest pockets (lined in our softest fleece) that you can use as hand pockets, as well as side vents for easy movement. Adjustable cuffs even keep the cold from creeping up sleeves. Yes, it's safe to say nothing is keeping us from an outdoor expedition — even if it’s a walk to the mailbox and back.
