The Burton Men's Japan AK 457 2L Insulated Jacket delivers fiery warmth and next level waterproofing for facing down Arctic cold blasts and snowpocalyptic storms. Previously available only in Japan, this jacket is now exclusively available through Backcountry. com in the United States. Pick one up today for high levels of warmth and waterproofing before shredding through single digit temperatures and deep cold smoke powder. Two layer Gore Tex construction and fully sealed Gore Seam tape ensure exceptional waterproofing and breathability, within a durable design that's resistant to daily wear and tear on the mountain. Its water resistant ripstop lining 15D keeps outside moisture from compromising the down insulation. In fact, you'll find 800 fill white goose down insulation for the highest warmth per weight of any Burton jacket available. Plus, its stretch shirring along the down insulation moves with your body to accommodate all of your surf slashing antics on the slopes. New for this year, Cohaesive embedded hardware along the hood and hem cinch integrate directly into the jacket's 2 layer fabric for robust strength and stealthy aesthetics. YKK T10 water resistant zippers keep outside moisture from working inside the jacket. The grippy powder skirt prevents chest deep snow from shooting inside with every glorious turn. Mesh lined underarm vents enhance thermo regulation on warmer spring sessions and demanding bootpacks beyond the resort. Other key features include adjustable cuffs with hideaway stretch grippers, as well as engineered articulation along the shoulders and sleeves for freedom of movement.
