Gear, other than helmets, I veiw much like shoes..... once they've been on my feet, there's not much likely hood someone else will want to wear them. :)
A jacket? maybe that would be different.... a racing weight leather jacket is not going to wear out for many, many years. Depending on how it was maintained, it might not even be noticable that someone else had used it.
Definitely a 'see it in person' deal, for me.... couldn't make a purchase like that sight unseen, without a really good return policy involved.
