Gear
Equipment
In many respects, you can never be too prepared, but there is always the issue of being weighed down by your equipment. Climbing gear is often essential to reach a lair, and some means of landing safely, a parachute or even a squirrel suit, is a must if you end up getting bucked. To be honest, the idea of using a saddle is comical, but it is not unknown. A better idea is to sew padding into your clothes.
Clothing
The debate is less protection and freedom of movement versus better protection and the agility of an armoured knight. A decent helmet and camouflage gear are pretty much the basics, both for obvious reasons. We've heard some Riders are starting to use flame-retardant clothing, but this tends to be very bulky and makes you stick out like a sore thumb. If worried about the heat, the best compromise is the gel stuntmen and women use in films.
First Aid
It happens. Riding several tons of a mean, fire-breathing, flying machine means you're going to hurt. Scale cuts [remove hyphen], wing and tail lashes, various degrees of burn, and even allergic reactions to the dragons themselves occur. So you better have some well-equipped ground support ready to patch you up.
Stuff
You know the drill: water, maps, and a compass... Essentials if you're going on any trek that is likely to take you far off the beaten path.
