What Our Gearhead® Experts Are Saying: "I bring this puffer on every winter mission because it balances featherlight packability with serious warmth. The Pertex shell really holds up against wind, and the draft tube is a smart touch that saves frustration when I’m layering in the cold." When the mountains turn bitter and the cold lingers in the valleys, the Florence Marine X Lava Down Puffer keeps us warm from summit pushes to frozen nights at basecamp. Its Pertex Quantum fabric draws inspiration from the strength and lightness of military parachutes, giving us a durable shield that traps warmth without extra weight. Inside, lofty 850-fill goose down offers superior insulation, compressing easily into a pack but expanding quickly when we need reliable warmth. The thoughtful details—like an adjustable hood, hem cinch, and grosgrain draft tube—make the Lava Down Puffer more than just a jacket; it’s a dependable tool against winter’s bite.
