I used this a few times in the past and then kept it at home. There are no noticeable stains, but the part where the strap attaches in the fourth photo is slightly dirty. Please understand. It has a cooling function inside. It can also be used as a regular pouch. ⚠︎︎ Immediate purchase is welcome ⚠︎︎ Stored at home
