Ridiculously warm. Surprisingly wearable. Built for winter.
The Puffinator is our warmest down jacket, designed for 10–30°F days with 800-fill down and a serious warmth-to-weight ratio. A matte recycled nylon shell blocks wind and a PFAS-free DWR sheds snow and light moisture to keep the loft performing.
Pit zips let you dump heat fast, and the two-way front zipper adds venting and harness compatibility. A dialed hood and hem seal out wind, and the pocket layout is built for winter: soft-touch hand pockets, a chest media pocket, and internal stash pockets for gloves and goggles. Expedition-ready warmth for backcountry skiing or winter mountaineering.

Wash / Care Instructions
Like all down jackets, two best practices make these last a very long time:
- Don’t wash it unless you actually need to. Spot clean first. A gentle wipe with a damp cloth goes a long way.
- Don’t store it compressed. Keep it lofted and fluffed whenever possible so the down stays happy and the jacket stays warm.
If you do need to wash it:
Our premium down deserves a little extra love. Use a down-specific detergent, wash gentle/cold, then dry low and slow with dryer balls to bring the loft back. Make sure it’s 100% dry before storing.
