Light Warmer Kochi Jacket

Fit & Size

Model: Height 187cm / 6'1" | Wearing: URBAN GRAY / 3

Features

An insulated jacket 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 and sleeves 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.
• Pre-shaped sleeves improve mobility, while thumbholes reduce sleeve bunching during runs.
• Comes with a stuff sack for compact portability.

About size dimensions (actual size)

Important notes

• Size dimensions are measurements of the final products.
• All size dimensions given are outer measurements of the product laid flat on a flat surface.
• Size dimensions and nude sizes are different measurements.
• The product tag displays nude sizes and not the size measurements.
• The outer dimensions are measured by hand. Therefore, there could be a slight difference (1~2cm) depending on a product.

Measuring

• Outer dimensions of stretch items are measured unstretched.
• Collar is not included in the measurement of collared items.
• For items with frills, gathers, and pleats, the outer dimension is measured with items stretched flat.
• The outer dimensions of down jackets are measured with down pressed flat.
• We recommend measuring items you own to compare specs for figuring out your best fit.
