The Woolcloud Snapshirt is a natural-technical marvel. This is not a jacket but an insulated shirt that is meant to be worn close to your core. Filled with lightweight Duckworth WoolCloud insulation inside a shell of 40 denier Nylon. The traditional shirt styling lends itself to everyday wear around town with the secret high-performance ingredient of lightweight wool fill to keep you warm. The natural wool fill will not clump, or pack like down over time and is extremely breathable. Shirt fit, snap chest pockets and zippered side pockets. Made in USA.
