We built the Nano Puff Vest 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. Made in a Fair Trade Certified factory.

• Regular Fit
• Lightweight 100% recycled polyester ripstop shell has a durable water repellent (DWR) finish made without intentionally added PFAS to shed light moisture
• PrimaLoft Gold Insulation Eco 100% postconsumer recycled polyester with P.U.R.E. (Produced Using Reduced Emissions) technology provides excellent warmth for its weight and stays warm when wet
• 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

• Center-front zipper has a wicking interior storm flap and a zipper garage at the chin for next-to-skin comfort
• Two zippered handwarmer pockets have cleanly finished zipper garages; an internal zippered chest pocket doubles as a stuffsack with a reinforced carabiner clip-in loop
• Drawcord-adjustable drop-tail hem seals in warmth; made in a Fair Trade Certified factory, which means the people who made this product earned a premium for their labor
