what is the best way to wear motocross racing pants?

only crazy hillbillies wear pants under pants! Just wear either your "baggies" or "in the boot" style Motocross pants with underwear. Some people wear a padded short underneath for extra protection. If you are a male, they make special riding underwear that are moisture resistant and hold the boys in a good location. The super baggy boxers are usually a bad idea. or so says my husband! Personally I wear comfy boy short underwear under my pants. long-johns too if it is freezing out!

Depending on the weather, I usually throw on a thin pair of shorts or something underneath. On a hot day I can stop and take off the pants for a little while, maybe go swimming. During colder weather, I have a thin pair of thermal underwear made out of Thinsulate that works pretty good. I will agree that on your head would make riding pretty difficult.

Depending on the weather. If it's hot, no pants (Lycra) underneath. A good pair of vented pants is all you need. In cold weather, Lycra leggings will hold in some body heat to keep you warmer. MX is an active sport so remember, you don't need too many layers or you will burn up.

Who needs pants?

I wear baseball sliding shorts underneath with a cup. Change the shorts between motos...like a breath of fresh air.

Preferrably on your lower torso. You look pretty stupid with them pulled down over your head.

your size with pads the way they are supposed to be worn.

hell any way you want to

NOT ON YOUR HEAD DUMMY
