MILLET Alpha Light Sweat II Jacket - Women's Size S (US XS) Purchased 2 years ago for the snowy mountain season for about ¥16,000 and used for 2 seasons. Used about 10 times as a mid-layer, so it's in good condition. For reference, it was a perfect fit for someone 153cm tall. From the official website: A base/insulation jacket with heat retention, breathability, and stretch, wearable all day long, from the city to the mountaintop. A high-performance insulation jacket that always provides comfort in active scenes, from the field to everyday life. The fabric, which sandwiches Polartec(R) Alpha(R), a mid-layer with excellent heat retention that prevents you from feeling cold and excellent breathability, between a quick-drying Drynamic Heather Mesh Knit material, allows you to stay comfortable whether you're standing still or moving in the cold. The thin and highly stretchable fabric fits the body easily, allowing for a variety of layering patterns, such as wearing it alone over a base layer or combining it with other mid-layers. This is a high-performance, multi-functional thermal layer that serves as the base for Millet's new layering proposal, "Insulation Pairing," which allows you to customize the layering of insulation according to the season and weather, enabling a wide range of delicate temperature and humidity adjustments. ■Color: HE NAVY (6357/HEATHER NAVY) ■Weight: 280g ■Material: Heather Knit 100% Polyester × Polartec(R) Alpha 40 100% Polyester (72% Recycled) ■Equipment: ・Polartec(R) Alpha(R) (72% recycled), which is excellent in breathability, stretchability, and quick-drying properties, is used for the mid-layer. ・Suppresses stuffiness and supports high exercise. ・Can be worn for a long period from autumn and spring to cold winters by combining it with other highly breathable mid-layer jackets. ・Soft, stretchy, and comfortable to wear. ■Functions: Stretch Quick-drying Lightweight ■Features: ・Moderate heat retention ・Breathability and quick-drying properties ・Stretchability Gender: Women's
