Patagonia say - The Nano-Air® Light Vest was made to be worn for the entirety of your aerobic, start-stop mountain activities, so you’re never slowed down by having to change layers. Stretchy and breathable FullRange™ insulation dumps excess heat when you’re working hard and keeps you warm when you’re not. Made in a Fair Trade Certified™ factory.

Stretchy, Breathable Fabric - The 100% recycled polyester ripstop shell and lining fabric offer mechanical stretch, exceptional breathability and improved abrasion resistance, with a durable water repellent (DWR) finish made without perfluorinated chemicals (PFCs/PFAS) to resist light moisture; the microtexture keeps fabric from sticking to the skin for versatile comfort

FullRange™ Insulation - 40-gram FullRange™ 100% polyester (93% recycled) insulation delivers outstanding mechanical stretch and air permeability (35 CFM), allowing excess heat to move away from the body

Built for Mobility - Articulated patterning and strategically placed, low-profile quilting combined with stretchy fabric and insulation provide an exceptional range of motion for unhindered movement
