What Our Gearhead(R) Experts Are Saying:"This is the puffer I bring when I know it's going to be brutally cold. The Pertex fabric is light but tough, and it lets the down loft fully so the warmth-to-weight ratio is incredible. I like the packable design-it stuffs into its own pocket for when I need to stash it, but when I'm wearing it, it feels like pure warmth without bulk."When the mercury drops and conditions turn harsh, the Florence Marine X Pertex Climashield Puffer Jacket keeps us warm and ready for the mission. Built with Pertex Quantum ripstop, this ultralight yet rugged shell allows the premium 850-fill down insulation to loft fully, maximizing warmth without adding weight. At just 332 grams, it delivers serious alpine protection in a featherweight package. Designed for expedition-level performance, the down-filled draft tube along the zipper prevents heat loss in a vulnerable spot, while a rear-adjusted hood and adjustable hem lock out biting winds. The C0 DWR coating sheds moisture without PFAs, giving us reliable weather resistance with an eco-conscious edge. When conditions shift, the puffer stuffs neatly into its own pocket, making it easy to clip to a pack or stow away until the cold sets back in. From static belays to long, frigid pushes, the Pertex Climashield Puffer offers a rare balance of packability, warmth, and durability. It's the piece we trust when mobility matters but warmth is non-negotiable.
