The main body material uses master-piece’s original fabric “MASTERTEX-09™,” which combines durability, water resistance, and water repellency.
This fabric is woven at a certified factory that meets INVISTA’s CORDURA® brand fabric production and quality standards. It uses double-twisted yarns with 840d warp and 420d Hollofil Air™ (66 nylon hollow fiber) weft, arranged in pairs. The fabric meets CORDURA® brand standards and offers excellent resistance to abrasion, tearing, and wear.
The reverse side is PU-coated and laminated with the special breathable waterproof film L-VENT®, further enhancing water resistance. Combined with tricot nylon, it forms a three-layer structure.
The auxiliary materials consist of two types of leather and fabric. The leather used on the front face is made from carefully selected fine-fiber hides, oil-tanned to create a water-repellent velour leather finish.
As it has no grain layer, it offers excellent breathability while maintaining thickness and firmness. Its distinctive surface features a soft pile with a warm appearance.
The leather used for other parts has passed the monitoring tests of 3M™ SCOTCHGARD® for water and stain resistance. High-quality domestically produced steer leather is carefully selected, and during the tanning process, a 3M™ waterproofing agent is added to the drum, allowing it to penetrate deep into the leather.
After dyeing and oiling to create the base, a 3M™ waterproofing agent is also sprayed during the finishing stage, further enhancing water resistance.
Since the monitoring tests are conducted even after abrading the surface, the effectiveness does not diminish.
Materials used on the bottom and other areas include INVISTA’s 1680d CORDURA® Ballistic nylon, which offers approximately five times the abrasion, tear strength, and durability of standard nylon. The reverse side is PVC-coated to further improve strength and water resistance.
In terms of storage, a variety of pockets of different sizes are provided both inside and outside, designed for ease of use in both on- and off-duty situations.
