Originally designed for climbers in need of a weather-resistant, lightweight, and packable midlayer, the Nano Puff quickly became a go-to favorite for any outdoor pursuit. Its secret lies in PrimaLoft® Gold Insulation Eco, made with 100% postconsumer recycled polyester and P.U.R.E.™ technology that reduces emissions during production—delivering incredible warmth-to-weight performance that stays effective even when wet.
Refined for improved mobility and comfort, this jacket features an evolved fit, durable horizontal quilting, and a longer body length for easy layering. Whether worn as an outer layer on brisk days or tucked under a shell in harsh conditions, it seals in warmth while staying feather-light. Finished with smart pocketing, packability, and Fair Trade Certified™ craftsmanship, it’s engineered to perform on the mountain and in everyday life.
