This season, J.Crew is stuffing its puffers with eco-friendly Primaloft--a breathable and lightweight, but still very warm filler originally developed for the U.S. Army. The result? A nonbulky layer that's perfect for those blustery winter days. (This one also features tons of supersmart details, like a water-repellent shell, thumbholes in the cuffs and snap-closure straps for mittens.) Color is metallic Blue Size 4-5 Primaloft insulation luxe Zip closure and snaps on top Flap pockets. Fleece Lined and lined pockets Dry Clean
