Boulder’s selection of SAXX  underwear are produced from ultrasoft Bamboo. Brand founder Trent Kitsch was wearing a survival suit for three days and experienced, what most men do, discomfort and irritation. He realized that there had to be a better way to design men’s underwear. Trent developed the concept behind SAXX underwear and its ergonomic comfort pouch: A boxer brief with two parallel polyester/spandex mesh panels that offer a barrier between a man’s package and inner thigh.
