Don't forget some sturdy suitable footwear, either cleats, astroturf boots, soccer/rugby boots or, what I use, lightweight hiking boots (I like the ankle support and the fact that their light, breath and are waterproof, grippy and tough as, well, old boots)! Your white Nike trainers are gonna get mullered
Meet with other players, ask what they are using and if you can try their kit, they may even have some spare to sell! But for Gawds sake don't get lumbered with someone's cast off poopoo old spider (or similar) that is only fit for the wheelie bin!
