Its right in the name, the The Burton AK Baker Hooded Down Jacket is built for the alpine. Ok so it is only kinda in the name, but it is absolutely in the details. Underarm zips help you dump excess heat while you change over on the ride, the adjustable hood traps heat and seals out winds, while the 800 fill down ensures we can stay warm in the harshest winter weather-with the help of a waterproof shell.
