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.

Features

• 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 and armhole fit provide greater mobility and comfort; a slightly reshaped fit and a longer body length offers easier layering

• 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
