The Fitz Roy Down Jacket pairs a recycled nylon ripstop shell with 800-fill Responsible Down Standard down, so it holds real heat without piling on weight. A DWR finish made without intentionally added PFAS keeps the shell ready before weather turns, and the regular fit leaves room to layer a midweight top underneath on the coldest days. What Our Gearhead(R) Experts Are Saying:"I notice how little this weighs the second I pick it up, but it holds heat the moment temperatures drop at a belay or a trailhead stop. It's the jacket I reach for when I need warmth fast and don't want dead weight in the pack."
