Your brain
From KayakWiki
Ok, it may be silly to mention "your brain" as a piece of safety equipment, but its actually a useful concept. Most emergency situations are avoidable with a little forethought.
The best way to be safe when you paddle is to avoid doing something stupid. Read Sea Kayaker's Deep Trouble. Notice how many people died because they were paddling without a PFD or paddled in frigid waters wearing jeans and a t-shirt. You can own all the safety gear in the world and it will do you no good at all if you don't use your brain.
