I'm going to get completely fucking lambasted for this but just go ride. Fuck knee pads. I understand some peoples need for a helmet, but knee, elbow and spine pads?? God-fucking-damn, just stay home. Here's the safety gear I wear snowboarding: nothing. Just be somewhat careful.
If you have some fucked up knees or something I apologize. But if you don't then I don't understand why you need pads.
