nahe: Nahe Dry Bag 2-Way Color: Yellow Size: Width 400 x Height 440 x Depth 7 (mm) Used a few times as an onsen (hot spring) bag after purchase. A dry bag with water-repellent treatment. It uses high-density ripstop nylon, also used for outdoor goods, and is characterized by its thinness, lightness, and excellent durability. Seam tape is applied to the stitching, preventing water from seeping in from the seams, making it useful at the gym or sauna. Thank you. Ripstop nylon DCF Dry bag Stuff sack SEA TO SUMMIT mont-bell
