its shoving your balls up inside you
Helmets have pads on the inside and can be blown up to fit the player.
Yes, quarterbacks do have radios inside their helmets that their coach can tell them what to do. But quarterbacks are not allowed to talk to them for a time period.
depends on the helmet. Its just plastic on the outside, it is the shape that helps to dispense impact. Inside there can be a variety of materials. Foam and Styrofoam are in most of the low end helmets, while a lot of the pro helmets have an air cushion system. The "plastic" is polycarbonate.

I play football so I know about football helmets. They are hard on the out side and soft in the inside. There are pads lined in the helmet. Some brands of helmets have an air tank that you fill with air to make it tighter. There is also the face mask that protects the face, a chin strap that holds the helmet on, and a mouth guard to reduce concussions and protect your teeth.
there is air in a football.
if you're talking about comparing it to football helmets: EVERYTHING. Its lighter; there's more room; little, but enough padding inside; there is plastic at the bottom of the facemask. It just protects your head enough since you arent charging head first at anyone. Its also illegal in lax to go head first into anyone for any reason. if youre taling about bike or motorcross helmets: look for yourself :P
air is in the football
