The lining uses a four-layer insulated fabric, making it soft yet durable. Also, since it's a washable insulated fabric, you can hand wash it when it gets dirty. (When using a washing machine, please use a laundry net to prevent the ribbon from getting caught.) The width of the gusset has been made smaller to easily accommodate ice rings. Besides that, it can be used year-round for various purposes, such as for snacks, rice balls, juice packs, and pouches, thanks to its insulation and cooling properties★ Also, it has a tab, so you can attach a carabiner or similar item if you like. 《Ice Ring 20》 Size (approx.)
