This page lists the kit that you need to train and play for rugby. On match days shorts, shirt, and socks are provided by the club.
Essential for muddy conditions. Some people use football boots, but studs on rugby boots tend to be a slightly longer. Comfort and support are most important.
Rugby shorts are made of a stronger material than football shorts to withstand the grabs in the game. It's important for forwards to ensure the shorts don't restrict movement.
Like the shorts the shirt must be able to withstand grabbing and tackling. 'Traditional' rugby shirts of cotton will get very wet during training.
These help prevent injury to the mouth and jaw. They must be moulded to shape before use, so don't buy them on the way to a match/training. Opro are a popular brand - and their fitting video is here
