Used 4-5 times, selling because I bought another one. Still in beautiful condition. 【master-piece/masterpiece】face Front Pack ¥14,850 Color: Navy Material: Nylon Made in Japan Product Description: The main body material is a lightweight nylon woven with 70d warp threads and 160d weft threads, laminated with a special microporous membrane film (Toray Co., Ltd. Breathatec®) on the back, and bonded with tricot nylon, providing high water repellency, breathability of 8500g/24hr level, and a water resistance of 11000mm level. The special microporous membrane film in the middle layer has very fine pores of 1-30 micrometers, which prevents water droplets while releasing vapor. It is a material that combines high water resistance, durability, and lightness. It is shaped to fit the body when held in front of the body, and is designed to be used like a front pocket. It has a drawstring bottle pocket, allowing you to separate the main storage and beverage bottle. It also comes with a tape loop that can be used as a towel holder and a carabiner, so you can expand the usage as you like, such as hooking a key ring. Breathatec. WATERPROOF & COMFORT DRY The breathable waterproof material "Breathatec" is a high-performance material that repels water on the fabric surface, and has both water-repellent/waterproof performance and the ability to release moisture accumulated inside to the outside. Due to the microporous structure of the special polyurethane formed in the middle layer, the surface of this membrane has a porous structure with fine pores of 1-30 micrometers, so water droplets cannot pass through this membrane, and moisture passes through and is released to the outside.
