Ultra-Light Windproof Travel Jacket Down Proof Fabric

This Ultra-Light Windproof Travel Jacket Down Proof Fabric is woven with 70D ultra-fine nylon fiber, weighing only 48 grams per square meter. After folding, it can be easily stored in a palm-sized portable bag, but it can provide the same tear resistance as traditional 600D fabric. ​

The windproof performance comes from its special twill encryption process, with a warp and weft density of 320 strands per inch. Combined with the fluorine-free water-repellent coating in the post-finishing stage, it can effectively block gusts below level 8 from directly penetrating, while maintaining a breathability of 0.015 cubic meters per second to avoid stuffiness and sweat accumulation during exercise.​

Anti-down drilling technology is the core advantage: the surface of the fabric is treated with 0.3mm micro-calendering to form a dense fiber gap barrier, and the 3mm ultra-fine rubber strip hot pressing process at the lock edge is tested to be rubbed continuously for 500 times at -15℃, and the down drilling rate is still less than 0.02 strands/square centimeter, which is much better than the industry standard of 0.1 strands. ​

A 1cm wide double-thread hemming seam is reserved on the edge of the fabric, which is suitable for the No. 9 round needle of a regular household sewing machine, so that users can modify the size according to their needs, which is especially suitable for outdoor enthusiasts to DIY lightweight warm equipment.
