The Mountain Equipment Men's K7 Down Jacket is your key to success on alpine ascents or Arctic explorations in frigid temperatures. Mountain Equipment stuffed this jacket with some of the lightest, loftiest, and softest 750 fill down available, and the jacket's box wall baffle construction eliminates cold spots. The Drilite Loft II shell is durable despite its lightweight appeal, and it's completely windproof and highly water resistant to protect you against whatever weather you might climb in. The K7 also features a hood with an elasticized lining that hugs your head for a snug fit, and you can cinch it tightly with a helmet on or not. Hook and loop cuffs prevent any needed warmth from escaping, and the hem has a dual tether drawcord for better adjustability.
