Light Warmer Kochi Vest

Features

An insulated vest designed for trail running, balancing lightness, breathability, and durability—ideal for high-output activities where sweat management is key.

• Main fabric is Pertex Quantum Air Diamond Fuse, offering lightweight durability and breathability, with high snag and pilling resistance to reduce wear from pack friction.
• Insulated with breathable, stretchable 3DeFX+ that flexes with body movement.
• Sweat-prone zones are left uninsulated and instead use Octa fabric, which combines a brushed surface and smooth backing for targeted comfort and breathability.
• Flat surface of Octa is used underarms for smooth movement; brushed surface is used inside the collar for added warmth.
• All layers—outer, inner, and insulation—are breathable to enhance comfort during perspiration.
• Laser-cut ventilation holes at the center back help release trapped heat and moisture.
• Comes with a stuff sack for compact portability.
