This wind shell utilizes a unique, ultra-lightweight, and extremely thin material. Lightweight design is pursued in every detail. While preventing wind penetration, it effectively releases stuffy heat, keeping you dry even during intense exercise. It's a pocketable design, achieving a storage size that fits in the palm of your hand, making it ideal for trekking, running, and other activities. The silhouette is slightly tight to reduce flapping in the wind.
