Whether you're wearing it under a shell, storing it in your pack as an emergency layer, or just strolling around town, there's one thing that's guaranteed: warmth. This down jacket features weather-repellent ripstop fabric and ultra-premium 600 down for breathable, radiant heat. If your ride gets too warm, use the venting Pit Zips™ for a quick release of excess heat. A zippered chest pocket is the perfect solution for storing your valuables. Whatever and wherever you're headed, don't forget your Burton AK BK Insulator Jacket - you'll regret it if you do.
Face Fabric
20D Ripstop Nylon - Denier is a unit of measure for the density of the fibers. The higher the number the softer and stronger the fabrics will be. With a rating of 20D for Ripstop Nylon, you achieve a durable and super soft garment.
Durable Water Repellent
90/10 Down Ratio - Down to regular small feather ratio. The higher the first number, the better the quality of your garment is. 90/10 is about as good as it gets!
600 Fill Power - The fill power indicates the puffiness of the down garment so the larger the number, the better the insulation. Generally, a garment with 500+ fill power is exceptionally warm and compressible.
[ak] Fit - Burton’s [ak] fit is designed with performance in mind. The [ak] fit features articulation throughout the garments construction. This garment will provide you with room for a light to mid-weight layer underneath.
Fleece-Lined Handwarmer Pockets
Zippered Chest Pocket
Underarm Vents - Burton’s Pit Zips™ can be easily accessed for a quick cool down.
