An exotic saddle is like a normal saddle of the same sort except that it is designed for an unusual mount. Exotic saddles come in military, pack, and riding styles.
A military saddle braces the rider, providing a +2 circumstance bonus on Ride checks related to staying in the saddle. If you’re knocked unconscious while in a military saddle, you have a 75% chance to stay in the saddle (compared to 50% for a riding saddle).
A pack saddle holds gear and supplies, but not a rider. It holds as much gear as the mount can carry.
The standard riding saddle supports a rider.
