The Women's Patagonia Nano-Air Light Vest is made of recycled polyester ripstop shell and lining fabric that offers mechanical stretch, exceptional breathability, and improved abrasion resistance, with a durable water repellent finish. The microtexture keeps fabric from sticking to the skin for versatile comfort and the 40-gram FullRange polyester (recycled) insulation delivers outstanding mechanical stretch and air permeability (35 CFM), providing warmth while allowing excess heat to move away from the body. This articulated patterning and strategically placed, low-profile quilting, combined with stretchy fabric and insulation, provide an exceptional range of motion for unhindered movement.

Chest is usually the best size predictor. However, if your hip measurement is larger, consider buying the size indicated for your hips.
Chest / Bust — Relax your arms, then measure around the fullest part of your chest and bust.
Waist — Bend slightly to one side to find your natural waist. This will be the crease created from bending. Then, stand erect and measure around your body at the crease points.
Hips — Stand relaxed with feet shoulder-width apart. Now, measure around the fullest part of your hips and seat.
