By adopting a thumb hole design at the cuffs, you can reduce excess fabric at the cuffs during running.
A lightweight, breathable, and durable down jacket designed for trail running. This insulation item is designed with the assumption of sweating during exercise. The main fabric uses Pertex Quantum Air Diamond Fuse, which is lightweight yet highly abrasion-resistant. It boasts high snag resistance and pilling resistance, reducing deterioration from pack abrasion. The insulation consists of 3DeFX+, which stretches and breathes, smoothly adapting to body movement. Areas prone to sweating are left without insulation, and the material features Octa, providing just the right amount of warmth, breathability, and stretch. Octa is made up of a micro-fleece surface and a flat backing, ensuring smooth flat surfaces under the armpits and sleeves while enhancing warmth with the micro-fleece side at the collar. All layers including the exterior, lining, and insulation are made of breathable materials to pursue comfort when sweating. Additionally, laser hole ventilation is placed at the center of the back where heat tends to accumulate, reducing moisture inside the garment. The forward set sleeves allow for easy movement in all directions, and the design offers high freedom of motion. The cuffs feature thumb holes to reduce bulk during running. It comes with a staff sack for compact carrying. *This is a women's model designed with a pattern that fits the female body shape.*
