The "magic jacket" — Patagonia originally built the Nano Puff for climbers who needed a weather-resistant, lightweight synthetic insulation layer that stayed warm when wet. The same features that earned that reputation make it the favorite midlayer for nearly every outdoor pursuit, from cold-weather hikes to travel days when one piece has to do most of the insulating work.
Built with a 1.4-oz 20-denier 100% recycled polyester ripstop shell and a DWR finish made without intentionally added PFAS, insulated with 60-g PrimaLoft® Gold Insulation Eco — 100% postconsumer recycled polyester with P.U.R.E.™ (Produced Using Reduced Emissions) technology. Excellent warmth for the weight, and stays warm when wet.
Standout features:
- PrimaLoft® Gold Eco synthetic insulation — warmth-to-weight performance that doesn't collapse when damp
- Signature horizontal brick quilting — durable, abrasion-resistant thread stabilizes insulation as outer layer or low-profile base under shells
- Evolved fit for mobility — improved shoulder fit and elbow articulation
- Center-front zipper — wicking interior storm flap, zipper garage at chin
- Self-stuffing chest pocket — internal zippered pocket doubles as stuffsack with reinforced carabiner clip-in loop
- Drawcord-adjustable drop-tail hem — seals in warmth at the back
Made in a Fair Trade Certified™ factory in Vietnam, meaning the people who built it earned a premium for their labor. Fabrics are bluesign® approved. The DWR finish is made without intentionally added PFAS.
Right pick for the customer who needs one synthetic midlayer to handle daily commutes, cold-weather hikes, and travel days where down would underperform in damp conditions. Stays in the daypack year-round.
