I am thinking of buying a Kevlar shirt, does anyone have one and what are your thoughts on them

I hear they are very hot, so if you live in a warm part of aus you'll probly suffer a bit.

Dont see too many crashers with shirts up over their heads ... leather is the go, but in summer a kevlar shirt may be better than other stuff people wear?

My 2c

Thanks for your reply guys, I was thinking of buying one so I dont wear my jacket when its too hot. My loving wife who is a nurse wont let me out without some sort of protection (she has remove gravel from too many bodies in her past and doesnt want me to go through the pain)
I have looked at the price from USA and are alot cheaper than OZ but they will not deliver.
