Don't worry though, we have a lot more Women's Vests in stock than that.

Breathable core warmth for high-output days, Nano-Air Light Vest balances insulation and airflow on the move

What Our Gearhead® Experts Are Saying:

"I use the Nano-Air Light Vest when I’m moving fast and don’t want to overheat. It’s incredibly breathable for an insulated piece and layers easily under a shell or over a light base layer. For touring, hiking, or any stop-and-go effort, it keeps my core warm without trapping excess heat."

We rely on the Nano-Air Light Vest when output is high and conditions are constantly changing. Designed by Patagonia for movement-driven pursuits, it’s the layer we grab for uphill travel, breezy ridgelines, and long days where temperature regulation matters more than max insulation. It adds just enough warmth to the core while letting heat escape as effort ramps up.

Built with lightweight, recycled materials and breathable FullRange insulation, the vest adapts to movement by stretching and venting naturally. A water-repellent finish sheds light precipitation, while the slim, articulated fit stays streamlined under a shell. With zippered pockets that remain accessible while wearing a pack or harness, it’s a versatile layering piece for technical, high-output adventures.

Inside The Nano-Air

Match The Weight To The Day

Nano-Air's FullRange insulation comes in three weights, 20 to 60 grams, matched to how hard the day is working the body.

Durable Water Repellent Finish

Resists light moisture, without intentionally added PFAS.

Lightweight Features

Tuned For Comfort

FullRange insulation holds body heat while letting excess heat escape through the outer fabric. A microtextured liner pulls moisture off the skin and dries fast, keeping the layer from feeling wet or clammy through changes in effort.

Nano-Air Light

Steady warmth for cold-condition days spent moving at a steady pace. Twenty-gram FullRange insulation under the arms manages heat where the body runs hottest, so the layer stays on through changes in effort.
