What style of underpants do rugby players wear underneath their shorts?

Rugby players typically wear form-fitting underwear, such as compression shorts or skin-tight shorts, underneath their game shorts. These undergarments provide support, minimize chafing, and help with moisture management during intense physical activity. Some players may also opt for specialized rugby shorts that include built-in padding for additional protection. It's important for players to choose options that allow for freedom of movement and comfort while playing.
