Initially, if the Rookie Riders program is being offered in a gym class or recreation centre - and horses are not involved - normal gym wear is the only requirement for participants.  The gym part of the program includes rolling, jumping, mounting a barrel and general gym based moves and games. Clothing that is not too loose and flappy, and flexible and well fitted is all you need!

If joining a rookie riders program that includes horses and participants will be riding horses during the course, the most important item that cannot be ridden without is an ASTM certified riding helmet. Wearing a helmet to ride a horse is the law for minors in Ontario and is strongly recommended for all adults. Riding helmets are specifically designed to protect against the types of head injuries an equestrian could experience, without interfering with their ability to ride safely.
 
While it’s tempting to buy a used helmet, it’s essential to purchase a new helmet that you know has no structural damage that may compromise your safety. A reputable tack store (equestrian apparel store) will carry certified helmets and will be able to assist you in selecting a properly fitting helmet that meets your needs.
 
Investing in a pair of riding boots is a good idea, but it’s not essential for your first few lessons. Make sure that the footwear for riding has a half-inch to one-inch heel to prevent a foot from becoming caught in the stirrup. Also, make sure the boots worn do not have a wide, thick sole, as these can make it difficult to remove a foot from the stirrup. Anytime people work around horses, boots should be worn.
 
Fitted pants, preferably with no in-seam that can rub legs, will be sufficient when first starting out. It can be tempting to wear shorts during the hot summer months, but they offer no protection to legs, which will be pinched and rubbed by the saddle. Avoid thin or loose-fitting pants, like leggings or jogging pants, which can be slippery on the seat of the saddle.
 
Avoid loose-fitting clothing, hoodies, jewellery or scarves, which could get caught while working around the horse or mounting and dismounting. Shirts should be tucked in for both safety and overall neat presentation.
