The main body fabric uses master-piece’s original high-performance fabric “MASTERTEX-09™,” which offers durability, water resistance, and water repellency.
Produced at certified factories that meet INVISTA’s CORDURA® brand fabric production and quality standards, the fabric is woven using two twisted 840d yarns for the warp and two aligned 420d Hollofil Air™ yarns (hollow 66 nylon fibers) for the weft. This construction meets CORDURA® brand fabric standards and provides excellent resistance to abrasion, tearing, and wear.
The reverse side is PU-coated and laminated with the highly breathable waterproof film L-VENT®, further enhancing water resistance. It features a three-layer structure bonded with tricot nylon.
Two types of leather and fabric are used for the auxiliary materials. The leather used on the front face is made from carefully selected fine-grain hides, oil-tanned to create a water-repellent velour leather.
As it has no grain layer, it offers excellent breathability while maintaining firmness through added thickness. The distinctive surface features a warm texture with a soft nap.
The leather used for other parts is carefully selected high-quality domestic steer leather. During the tanning process, a waterproofing agent from 3M is added to the drum to allow deep penetration into the leather.
After dyeing and oiling to form the base, a 3M waterproofing agent is sprayed again during the finishing process to further enhance water resistance.
This leather has passed the 3M SCOTCHGARD® monitoring test for water and stain resistance. As the test is conducted even after the surface is abraded, the effectiveness does not diminish.
For the base and other high-stress areas, INVISTA’s 1680d CORDURA® Ballistic nylon is used, offering approximately five times the abrasion, tear, and durability strength of standard nylon. A PVC coating on the reverse side further improves strength and water resistance.
Excluding the outer fabric, the shoulder pad features a five-layer cushion structure incorporating lightweight and resilient EVA resin, along with Asahi Kasei Advance’s FUSION®, which is also used in bedding and car seats.
FUSION® is an innovative three-dimensional knitted fabric developed by Asahi Kasei, featuring excellent cushioning by connecting two knitted layers with elastic threads. Its diagonal structure also provides outstanding shape stability.
