The main body is made of MASTERTEX-07, an original fabric with excellent durability and fastness, woven in a certified factory that meets CORDURA® brand fabric production and quality standards, using two strands of 210d 66 nylon yarn, warp and weft. The zipper is made of AquaGuard®, a YKK zipper with a polyurethane film laminated to the surface of the tape and treated to make it watertight. The bag has a 2-way design that can be used as a shoulder strap for your bag while traveling, or as a stand-alone sling bag when traveling. The attached tape is looped so that carabiners, key rings, etc. can be attached. The coloring of the fabric and the watertight zipper is typical of master-piece's casual series.
