This Millet Alpha Light Sweatshirt is perfect for the late autumn and winter seasons. It's a valuable piece of active insulation and outerwear for cold days. I'm selling it because it became too tight after I built up my chest muscles through weight training, so I bought a larger size. …… Insulated Sweatshirt Alpha Light Sweat This active insulation combines Polartec Alpha, a mid-layer with moderate warmth and high sweat-wicking performance, with a breathable knit material. It allows for versatile layering patterns, whether worn alone over a base layer or combined with other mid-layers. ● Material Composition Heather Knit 100% Polyester × Polartec® Alpha 40 100% Polyester (72% Recycled) - Color: Charcoal Heather - Size: M (Size Guide: Chest 88-96 cm, Height 165-175 cm) ★ Used approximately 5 times on mountain hikes in snowy conditions, and the condition is good.
