The braies were worn as underpants beneath trousers. They protected against heat and permitted freedom of movement. These braies are fitted with laces, which enable the wearer to fasten them around the waist and legs and prevent them from slipping down. They are available in sizes XS–XXL and are crafted from 100% cotton.
