Nano Puff Vest delivers lightweight core warmth in a versatile, packable design
What Our Gearhead® Experts Are Saying:
"This vest is my layering secret weapon. It adds just the right amount of warmth over a base layer on cool mornings or under a shell when the weather turns. It’s light, packs tiny, and never leaves my pack."
We reach for the Nano Puff Vest when we need ultralight, breathable warmth without the bulk. Whether we’re layering it under a ski shell or tossing it over a flannel for morning coffee at camp, this core insulator keeps us warm without slowing us down.
Built with a recycled ripstop shell and filled with PrimaLoft® Gold Eco, this vest offers reliable warmth—even when wet. The slim profile layers easily, and the brick quilting not only improves insulation stability but also adds a signature look. The whole piece packs into its own chest pocket, making it easy to bring along on any mission, from alpine climbs to urban commutes.
