Ok, I opened up a can of worms. Let see if I can dig through all this mess:
1) Where did I get it? A friend for $20. My favorite though (and wait until you drool over this): look up Bohn Body armor. I was not awake earlier. Be prepared to say" THAT IS IT".
www.bohnarmor.comNow as for the heat: I too wear a cooling vest, but cannot see this working with the pressure suit. Honestly above like 85 I have to put the original floppy armor back in, the vest on and pull the plexiglass off the rifle base. And then go as high as I can, and don't come back down until the sun goes down.
Other choice: The Icon field armor flows so well that I cannot see it being a hindrance. Works great for my legs year round, and you know how hot a C10 riders legs get.
As for the on road/off road thought. I bet you go harder and faster on the street. Why not be prepared?
Think it is covered, and yes, my suit lets my gut hang out. There, that does it.
