Rugby shorts

Rugby shorts are a type of shorts that are worn while playing rugby. They are designed to take the strains of the game and have traditionally been made from cotton, in 1971 Polyester shorts were worn by international rugby teams such as Wales.

Features
Shorts should be comfortable, as tight shorts increase the chances of sustaining a serious injury. The longer and baggier shorts are, the easier it will be for opponents to pull an opponent back. The colour and style of shorts are determined by the players club.

Purpose
Rugby shorts must be able to withstand punishment and should be thick enough to provide some protection while playing. Most have pockets and many have a drawstring to prevent them coming down when tackled. While the most popular material has been cotton, modern shorts can also be made from higher grade polyester with reinforced seams. The use of these shorts is increasing as they are lighter, more durable, more comfortable, and better retain their color compared to traditional cotton shorts.

Tag rugby shorts are generally lighter due to the non-contact nature of the sport and have tags attached with velcro patches.

Underwear
The use of hard plastic padding of any kind, including abdominal guards (box), is forbidden in most leagues. However, unpadded jock straps can be used to provide support and prevent groin injuries. In the United States, the high-padding of American football has influenced some junior leagues to allow, or in some cases require, abdominal guards and jock straps.
