The Nano Puff® Vest was designed for climbers seeking a weather-resistant, lightweight, and packable synthetic insulation layer that remains warm even when wet and endures season after season of use. These same features have since made it a preferred midlayer for nearly any outdoor activity. Now updated with fit refinements to enhance mobility, it features 60-g PrimaLoft® Gold Insulation Eco made from 100% post-consumer recycled polyester with P.U.R.E.™ (Produced Using Reduced Emissions) technology, along with a 100% recycled polyester shell and lining. Manufactured in a Fair Trade Certified™ factory.

Features

• Made with a lightweight 100% recycled polyester ripstop shell featuring a durable water repellent (DWR) finish, free from intentionally added PFAS, to shed light moisture.
• Insulated with 60-g PrimaLoft® Gold Insulation Eco, made from 100% post-consumer recycled polyester and produced using P.U.R.E.™ (Produced Using Reduced Emissions) technology, offering exceptional warmth for its weight and maintaining insulation even when wet.
• A brick quilting pattern with horizontal quilted side panels, stitched with durable, abrasion-resistant thread, stabilises the insulation and enhances durability both as a standalone piece and as a low-profile layer beneath shells.
• Refined shoulder and armhole shaping improves mobility and comfort, while a slightly reshaped fit and extended body length allow for more effective layering.
• The centre-front zip includes a wicking interior storm flap and a zipper garage at the chin for added comfort next to the skin.
• Two zippered handwarmer pockets feature cleanly finished zipper garages, and an internal zippered chest pocket doubles as a stuffsack with a reinforced carabiner clip-in loop.
• A drawcord-adjustable drop-tail hem helps seal in warmth. Manufactured in a Fair Trade Certified™ factory, supporting the workers who produced it with a premium for their labour.
