We have a few key items in our online shop which will help your player be a happy player. In our experience, young player's need to be suitably dressed for their activity so they can relax and enjoy it. All children are different though, and some never feel the cold (we have one of those, although he's 14 now and is still happiest in only one layer whatever the weather). Other children don't like to get mud or water on their clothes. some parents don't like this either and that's ok, we understand, that's why we strongly recommend the Kiddikicks waterproofs - a jacket and trouser set which is thin, breathable, roomy and waterproof. It fits perfectly over clothes and keeps everything dry and mud free. Take a look!
