The On Women's Climate Shirt is a lightweight performance layer designed to keep you comfortable through changing conditions. Built for running, hiking, and everyday movement, it balances warmth and breathability to adapt to your activity level. The moisture wicking fabric features a multi dimensional surface that helps pull sweat away from the skin for faster drying. A close fitting design with four way stretch allows the shirt to move naturally with your body without restriction. Thoughtful details like thumb holes and a quarter zip closure add convenience and coverage when you need it. With a contoured shape and secure storage, this shirt is ready for long efforts in cool or variable weather.
