These black yellow green Dave's choice jumpsuits are on fire! Small sizes, so please refer to the size chart to ensure the size you order is large enough, e.g., the 5XL will suit a weight of 175 pounds to no more than 202 pounds ( convert kg x 2.2 = pounds) and a 45" chest. That said, I would order one size larger to allow for a more loose fitting jumpsuit by ordering at least one size larger than your measurements. I would personally order a size 5XL to a maximum weight of 185 pounds and chest size no more than 42". Made from cotton...button closures, zipper fly, buttons on chest and back pockets. This jumpsuit will fade with washes to a cool vintage look as it wears over the years.
