at the races its full racing gear! most...all of the fast racers wear it. baird is in full leathers when its 107 deg. a lot of mx gear also. i wear kevlar sliders long sleeve shirt elbo and gloves and a open face so i can spit and pick my nose [old desert rider habbits] ride safe!
when i'm racing, i wear a full face Simpson helmet that's designed for top fuel drag racing. i bought it new from a swap meet for 25 bucks. it's normally $500+.
as dennis said, i wear full racing leathers i got off ebay for 200. they're black leather, with all the pads and plastic caps, but it breathes well, so i'm comfortable in the heat.
not exactly what i wear for a trip to the liquor store.
for daily riding i have a vintage police riot helmet. i was wearing that when i crashed. i was also wearing jeans, work boots, gloves, and a gas station jacket. i fractured one wrist and chipped two fingers on the other. if i didn't have gloves, probably woulda lost a lot of skin.
i was leaving work and rode 2 blocks when i crashed. the old "i'm just cruising around close to home..." way of thinking could get you killed.
and i'm guilty of it, too. i race my bikes up and down the street when i'm building or tuning them, often times in shorts and a t shirt with no helmet.
that's probably gonna change once i'm healed up. not smart full throttling an untested bike with no protection.
and just because you've been riding bikes for years and never landed on your head doesn't mean it can't happen...
all that being said, i'm still gonna wear my open face helmet on the street...
