This is a drawstring bag, exclusive to Superdry (極度乾燥しなさい) brand stores, which is not available in Japan. It's made of polyester, but the material is quite sturdy. You could compare the thickness to that of a thick swimsuit. I purchased this at a Superdry store in Guam a few years ago, but I never used it and have kept it in storage. The tag has been removed, but the rubber band that held the tag is still attached. There are no signs of wear on the corners or any overall dirt. Color: Jungle pattern (blue/green) Size: Approximately 45cm x 38cm Material: 100% Polyester Pocket: Inside, with Velcro closure #superdrysport #極度乾燥しなさい #スーパードライスポーツ #スーパードライ
