jacket sizing with separate back protector

[speedy21]

ive been looking at the forcefield back protector and am just wandering what size jacket/suit you guys wear when you use a separeate back protector, im medium for pretty much everyting so asuming that a medium leather jackets fit perfectly would the back protector go underneath it comfortably or would it be better to go up a size. i will probably buy the leathers first so would be difficult to try both on the same time, thanks guys

Best bet is to try it on yourself. It's a pain going down to the shop to try it, but it's the only way to get a definite answer, and it's worth it considering the potential cost of the kit!
