Jumping skis: Because of the precise nature of the sport, typical ski length is measured by a mathematical formula: The jumper's height plus 46% of the jumper's height. So a skier who is 178cm (5ft 10in) will use a custom-made ski that is 260cm long (178cm + 82cm).

Each jumper has a cord which attaches the ski to the boot. The cord detaches itself from the ski if the jumper falls to minimise the risk of injury.

Suit, helmet, goggles: Apart from the skis, the jumper's other key piece of kit is his suit.It is made from a thick, spongy material which fills with air mid-flight to increase hang time and distance. Competitors also wear a light protective helmet, ski goggles and leather gloves.
