Patagonia Mens Nano Puff Jacket

The Patagonia Nano Puff Insulated Jacket is a lightweight, packable men's insulation layer designed for climbers, walkers and everyday adventurers who need reliable warmth in unpredictable UK conditions.

Ideal for These Activities: Hill Walking; Climbing; Backpacking; Everyday Use

Originally developed for climbing, the Nano Puff has earned a reputation as a versatile all-round layer thanks to its impressive warmth-to-weight ratio and dependable wet-weather performance. It uses 60g PrimaLoft® Gold Insulation Eco made from 100% post-consumer recycled polyester with P.U.R.E.™ technology, helping it retain warmth even when conditions turn damp. A lightweight 100% recycled polyester ripstop shell is finished with a durable water repellent (DWR) treatment made without intentionally added PFAS to shed light moisture.

Designed for active movement, the regular fit has been refined with improved shoulder shaping and elbow articulation to enhance comfort and mobility. The jacket layers easily beneath a shell thanks to its low-bulk construction, while the quilted design helps keep insulation evenly distributed for long-term performance and durability.

The shell uses a 20-denier recycled polyester ripstop fabric, paired with a recycled polyester ripstop lining. Signature brick quilting and horizontal side-panel quilting stabilise the insulation, while a centre-front zip features an interior wicking storm flap and a chin guard for comfort. Two zipped hand pockets provide secure storage, while the internal zipped chest pocket doubles as a stuffsack and includes a reinforced carabiner clip-in loop. A drawcord-adjustable drop-tail hem helps seal in warmth when temperatures drop.

With bluesign® approved fabrics, recycled materials throughout and manufacture in a Fair Trade Certified™ factory, the Nano Puff combines proven outdoor performance with responsible production. It's a versatile investment for anyone seeking a durable insulated jacket that works equally well on the hill, at the crag and in everyday life.
