We don’t just say it, we live by it: Athlete Tested. Expedition Proven.™ It might look like a puffer, but this jacket has been put to the test in some of the harshest conditions on earth. That’s how we innovate. We find the crux, improve our beta and build it better. Adapted to the high alpine as a flexible mid layer or as an uncompromising outer layer, it thrives no matter where you take it. With highly compressible, water-repellent 800-fill ProDown™, you can move lighter and faster through the mountains or the daily elements. Engineered for mobility. Cut for precision. This is Summit Series. This is the Breithorn.
