Pound-for-pound, the hardest hitting and most breathable technical insulator anywhere. 100g Primaloft insulation and 20D micro ripstop nylon shell assure packability, while a combination of Polartec Power Grid and Schoeller softshell under arm allow the garment to stretch, breathe, and transport moisture better than any insulator you've ever met. One-handed hood cinch allows for on-the-fly adjustment. Fit is kept trim for functional layering.
