Discover the ultimate lightweight insulation layer for your outdoor adventures: the Nano Puff® Jacket. Originally designed for climbers who demand reliable warmth and weather resistance, this versatile midlayer is now a go-to choice for hikers, travelers, and everyday explorers.
Crafted with 60-g PrimaLoft® Gold Insulation Eco made from 100% postconsumer recycled polyester, it provides incredible warmth-to-weight performance and stays effective even when wet. The durable, 100% recycled polyester shell and lining feature a PFAS-free DWR finish to repel light moisture.
With its regular fit and improved shoulder and elbow articulation, the Nano Puff offers enhanced mobility and comfort. Horizontal quilting stabilizes the insulation for durability, whether you wear it as an outer layer or under a shell. Two zippered handwarmer pockets and an internal chest pocket—which doubles as a stuff sack—add practical storage.
Stay cozy with the adjustable hem that seals in warmth, and feel good knowing it’s made in a Fair Trade Certified™ factory. Weighing just 309g (10.9 oz), this packable synthetic insulation jacket is ready for any season.
Machine wash cold, tumble dry low. Made in Vietnam with bluesign® approved fabrics.
