We built the Nano Puff® Hoody for climbers who needed a weather-resistant, lightweight and packable synthetic insulation layer that could stay warm even when wet and withstand seasons of use. Ever since, those same features have made it the uncontested favorite midlayer for just about any outdoor pursuit. With fit refinements for improved mobility, 60-g PrimaLoft® Gold Insulation Eco 100% postconsumer recycled polyester with P.U.R.E.™ (Produced Using Reduced Emissions) technology, and a 100% recycled polyester shell and lining, this iteration of the Nano Puff reinforces why so many people call this the “magic jacket.” Made in a Fair Trade Certified™ factory.

Brick quilting pattern and horizontal quilted side panels with durable, abrasion-resistant thread stabilize insulation for greater durability as an outer layer and low-profile, low-bulk layering under shells.

Improved shoulder fit and elbow articulation offer better mobility; a slightly larger hood improves hood lift and is more comfortable at the chin.
