From stylish street piece to life-saving extra layer, Burton's AK BK Insulator Jacket offers powerful, ultra-packable warmth.
If you are one who is always cold, refuses to hide indoors, or spends a lot of time in the backcountry far from shelter, then the Burton [ak] BK Insulator Jacket isn't nice to have, it's a necessity. Ultra lightweight and extra-packable, the BK's weather-repellent ripstop fabric encapsulates a super-potent DRYRIDE Thermex 550 fill power down for breathable, radiant heat. Venting Pit Zips give all that heat a quick escape, while the chest pocket is perfect for your wallet, keys, and phone.
