Why are people so worked up on what others think? Do what you want to do and screw what anyone else thinks.
On topic, I ride in a one piece 98% of the time regardless of the type of riding I do that day. I've been down and jeans offer little protection, I don't want more scars from road rash.
I wear a one piece every time I go out riding; doesn't bother me in the slightest. I say go for it man, especially at less than half the price. As smokey pointed out, make sure it fits first.
so guys, do you ever go to a cafe, store, etc., in a 1 piece?...how weird does it get?...
Who gives a fuck? You look like hot shit.
This just about sums it up:
"Riding gear is a full suit of armor that is socially acceptable to wear in public. You walk into a Starbucks wearing your period authentic replica half-plate, and at best you're going to get some impolite stares; at worst, you're going to get a news piece with the headline "Police Fell Local Knight With Bear Mace, Mocking Laughter."
But you walk in there in motorcycle gear and, depending on how much the other customers want to piss off their father, you're either a responsible commuter or a naughty rebellion just waiting for a sexy coup."
