It seems to save a pinch in an emergency. I found a disaster prevention goods called "Moshimono Safety Set (cold protection sheet + portable toilet)" at LOFT, a general store for daily life.
A set that is useful when a disaster occurs and you are in a situation where you "spend in the cold outdoors" or "cannot use the toilet". "Waterless sanitary toilet (unisex, 2 times)" that combines a "cold-proof body wrap sheet" (140 x 210 cm, 1 sheet) that is wrapped around the body, a urine bag, a super absorbent polymer, and a disposal bag. "Is included. If you put on a cold-weather wrap sheet when using a waterless sanitary toilet, it will not only be a blindfold, but will also have the effect of reducing the noise when urinating.
A cold protection sheet and a portable toilet that you can leave at home, at work, or in your car. Why don't you consider purchasing while looking at the balance with your own disaster prevention goods? The selling price at LOFT was 684 yen (excluding tax).
