Triumph, the company behind a number of strangely innovative brassiere designs, just came out with a new undergarment to keep women cool during a hot summer day. The “Super Cool Bra” features built-in gel icepacks in each cup that remain soft while frozen, giving the wearer a “super cool feeling,” according to the Japanese manufacturer. And for whatever reason, the bra is designed to look like a fishbowl. What other bras have alternative purposes? From a bra with hidden pockets to one that double as a gas mask, we run down the most multifunctional underwear.
