The Puma Ecosphere's Down Sweater Jacket for Women packs quite a punch. The ultra insulating 800 fill goose down could trick you into thinking your torso is a pillow. Don't be fooled though this hybrid down jacket is for cold weather active performance, not sleeping. First of all, the ultralight, heat trapping down is treated to resist clumping when wet, so it's ready to head out into hostile environments. Puma knows that when you're working hard, a full down jacket can be too much, so it put three layer softshell fabric with a wicking grid backer on the sides and lower arms, ensuring both breathability and better range of motion. It also makes layering under a shell easier. The cuffs are knit from a hydrophobic fiber so they won't wet out easily, and dry quickly. Forgot your gloves' Don't fret: the waist pockets are lined with fleece for ultimate hand warmth.
