As warm as it gets.
If you have to ride in Arctic-worthy weather on a regular basis or you're the type of person that starts wearing hoodies as soon as it hits seventy degrees, then you need the Burton Women's Eden Down Jacket. The warmest jacket that Burton makes, the Eden will keep you out of the lodge and on the slopes no matter what the weather brings.
Stay toasty when winter brings its worst thanks to the 600-fill down insulation, which offers a higher warmth-to-weight ratio than synthetics so it's incredibly warm, yet lightweight so you don't feel weighed down when riding. You have your option of a sleek nylon ripstop fabric or a fuzzy, wool-like fabric, both of which are backed by DryRide Durashell to keep you dry. Taped critical seams prevent moisture from seeping in, and mesh-lined underarm vents allows you to shed heat when it gets too warm even for you. The contoured hood with a micro-adjust cinch shields your head from the storm when the weather suddenly turns on you. A removable stretch powder skirt with jacket-to-pant interface keeps the snow out on waist-deep days.
