Players also wear underwear as part of their standard kit. Other supports and protective items are allowed only within the rules and safety limits; synthetic compression tights and padded undershorts are not automatically permitted.
What can rugby players wear under their kit?
World Rugby’s 2025 Laws of the Game, Law 4 lists the standard playing clothes as a jersey, shorts and underwear, socks, and boots. It also expressly permits “Cotton blend long tights or leggings, with single inside leg seam under their shorts and socks.” That wording describes a specific garment and construction, not every item marketed as compression wear.
- Underwear: part of the standard clothing listed in Law 4.
- Long tights or leggings: the expressly named option is cotton-blend, has a single inside leg seam, and is worn under shorts and socks.
- Supports and dressings: washable supports made of elasticated or compressible materials, as well as bandages, dressings, thin tape or similar material, are listed as permitted items, subject to the full law and safety judgment.
The law’s wording does not establish that all-synthetic compression tights, or any particular commercial base layer, are allowed. Check the garment’s material and construction against the wording and your competition’s rules.
Is padded clothing allowed?
Law 4 prohibits shorts or leggings with padding sewn into them. It also bars items such as contaminated clothing, sharp or abrasive objects, jewellery, gloves, and clothing with specified rigid parts or projections unless specifically allowed. Even an item that is normally permitted can be rejected if the referee considers it a potential injury risk.

World Rugby’s Regulation 12 and applicable equipment specifications also govern protective and padded clothing. The technical specification describes body padding secured by a tight-fitting undergarment or inserted into compartments in an undergarment or jersey; that is not blanket permission to wear arbitrary padding. Verify that any padded item meets the relevant approval and specification rather than relying on a product description alone.
Which protective items are separate from base layers?
Law 4 lists categories that include headgear, shoulder pads or approved chest pads, a mouthguard or dental protector, shin guards, and limited ankle supports. These serve different purposes from a thermal or coverage layer, and their use remains subject to the law and any applicable equipment requirements. Do not assume generic padded gear is approved.

A mouthguard is worn in the mouth, not under clothing. World Rugby’s equipment guidance says a good mouth guard protects teeth and surrounding soft tissue and can prevent a broken jaw; that guidance is not a claim that a particular mouthguard prevents concussion.
