There are many ways to stay safe without using protective gear. Besides a helmet, rest of the injuries can be avoided. When you fall forward, land on your knees and get the habit of tucking your arms in and landing on your fore arms with your arms pointing up. When you fall backwards, bend your knees. When you do rails, remember to stay balanced. Detune edges. Avoid going on rails backwards if you're afraid of your board sliding out. Or you can shove your butt with butt pads and yes, your wrist guard will fit, but wrist guards are not an excuse to try to stop a fall with your hands. Always tuck your hands in so you don't snap your wrists.
