The goal isn't to block wind. It's to manage it. The Aerolight Wind Jacket keeps the cold out without overheating during extended movement. Ultralight, breathable, and packable enough to disappear into your pocket when the sun comes out.
How it fits into your System

The goal is airflow
Most wind jackets work well for about ten minutes. Then you start overheating, the inside gets sticky, and suddenly the thing meant to protect you becomes the problem. The Aerolight Wind Jacket was built to solve exactly that.

How to use it
A wind layer, not a warmth layer. On high-output days it does the job a midlayer normally would, without the weight or the heat. Packs to fist size when the wind drops.
