What Our Gearhead® Experts Are Saying:"I’ve taken the Lumina 200 on alpine missions and cold-weather hikes—it punches way above its weight. It packs small, layers easily, and the 1000-fill down is incredibly warm without bulk. It’s one of the lightest jackets I’ve worn that still handles real mountain weather."When we’re counting grams but not willing to sacrifice warmth, the Lumina 200 Down Jacket becomes our go-to layer. Built as the midweight option in the new Lumina series, it balances exceptional packability with powerful insulation, making it perfect for cold alpine starts, shoulder season summits, and travel days where space is tight but warmth is non-negotiable. With 1000-fill Italian down and a Pertex® Quantum shell made of 100% recycled polyamide, this jacket offers an impressive warmth-to-weight ratio and eco-conscious construction. Engineered down chambers optimize thermal performance, while elastic-bound cuffs and a low-profile hood keep the fit secure and heat sealed in. Toss it in your pack with the included stuff sack, and head into the mountains knowing you've got serious warmth in a featherlight form.
