I purchased these but never used them, so they've been stored. They still have the tags attached. This is a set of three sizes: S, M, and L. They can be used individually for everyday use, as bag-in-bags when traveling, or in various other situations. The material is nylon ripstop fabric, also known as parachute cloth. Thick nylon threads are woven in a grid pattern, providing tear resistance. Even if a hole appears, it's less likely to spread further, which is why this material is used in military ponchos and outdoor wear. The PORTER name tag uses reflective fabric that reflects light back to the source. Sizes: S: Width 15cm / Height 26cm / Depth 7.5cm M: Width 17.5cm / Height 32cm / Depth 8.5cm L: Width 22.5cm / Height 39cm / Depth 11cm
