It’s essential that you have your own to the following UK/ European safety standard: PAS 015 (1998 or 2011) and VG1, with BSI Kitemark.
America: ASTM F1163: 2004a onwards with SEI mark, Snell E2001 onwards with the official Snell label and number
Australia and New Zealand: AS/NZS 3838 2006 onwards with SAI Global mark
You will also need riding boots or boots and chaps (boots to have a heel and no laces). Breeches or jodhpurs are definitely the comfiest riding wear, and you are most welcome to wear a body protector or air vest, though this is not a requirement. Thereafter, we send a suggested packing list to guests with advice on layers etc.
