The Wave Quilt Down Jacket looks back to the puffer’s roots, when it was originally developed for high-altitude mountaineers seeking warmth with minimal bulk. Starting with that template, Relwen overhauled the design for durable, daily wear. The micro-ripstop shell repels water and prevents tears from spreading, while the responsible down fill delivers toasty warmth—in a footprint that easily packs down into its own left pocket.
