What truly makes the Men's Burton [ak] 2L LZ Down Jacket a more powerful puffy is that it's the only Burton down parka wrapped in fully waterproof and highly breathable GORE-SEAM taped GORE-TEX two-layer fabric. On the inside, responsibly sourced 800 RSD goose down fill cranks up the heat while keeping overall weight to a minimum. Brand new this jacket is currently $689. https://www.burton.com/us/en/c/ak-collection?prefn1=Warmth&prefv1=Heavy This is the warmest jacket Burton makes and it is in very good condition. There is some very minor wear around the left pocket (pictured) but no rips or tears. I am 5'11 and 150 pounds. It runs a little large so the size small fits me perfectly and is by far the warmest jacket I've ever owned. Plenty of vents as well and the Goretex will keep you dry all day.
