Patagonia Men's Nano Puff Vest

The Patagonia Men's Nano Puff Vest delivers core warmth with a conscience, but is it the right choice for your next adventure? This incredibly lightweight and highly compressible vest provides the perfect amount of synthetic insulation for a huge range of conditions, serving as either a sleek midlayer or a protective outer layer.

Best Used For

The Nano Puff Vest excels as a versatile layering piece for three-season use. It is ideal for chilly fall hikes, spring ski tours, and cool evenings at the campsite. Wear it over a base layer during high-output activities like rock climbing or cross-country skiing, or layer it under a shell when the weather turns wet and cold. Its packability also makes it an essential emergency layer to keep in any pack.

Key Features

Windproof 100% recycled polyester ripstop shell with a durable water repellent (DWR) finish.

Highly compressible 60-g PrimaLoft Gold Insulation Eco, made with 100% postconsumer recycled content, maintains 98% of its warmth, even when wet.

Brick quilting pattern with horizontal quilt lines on side panels stabilizes insulation and uses durable thread for abrasion resistance.

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.

A drawcord-adjustable drop-tail hem effectively seals in warmth.

Why We Like It

What truly sets the Nano Puff Vest apart is its unrivaled balance of weight, warmth, and environmental responsibility. While other vests may offer similar warmth, few achieve it in such a lightweight, compressible package that performs reliably when wet. The commitment to using 100% recycled materials for both the shell fabric and the PrimaLoft Gold Insulation Eco means you're getting top-tier performance with a significantly reduced environmental footprint. It’s a workhorse piece of gear that justifies its place in your kit through sheer versatility and a design that's been refined over years of real-world use.

Fabric/Material Composition

The shell and lining are crafted from a 1.4-oz 20-denier 100% recycled polyester ripstop with a DWR finish. Insulation is 60-g PrimaLoft Gold Insulation Eco 100% postconsumer recycled polyester with P.U.R.E. (Produced Using Reduced Emissions) technology.

Fit

This vest features a regular fit, which is neither too slim nor too relaxed. It is designed to be worn comfortably over a base layer or light midlayer, and it fits easily under a shell jacket without adding excessive bulk.

Sizing Availability

Available in Men's sizes from XX-Small to 3X-Large, subject to current stock.

Care Instructions

Machine wash cold on a gentle cycle. Use a mild detergent and do not use bleach or fabric softeners. Tumble dry on low heat with two or three clean tennis balls to help restore the loft of the insulation. Do not iron or dry clean.
