You're most likely going to have to go with a Kirkey or something along those lines. Can still get all the head, shoulder, rib, thigh protection options, but I can't see a Lajoie or any other big $$ full containment in the size you would most likely need (coming from a 6'1" 265lb guy when I started in Legends, so I feel i can say that without offending. My apologies if offense is taken).
The Lajoie is great, Would love to be able to afford one, but even if I could, I'm 99% sure I wouldn't be able to fit one in my ,car in my size, with all of the side impact bracing they incorporate. Don't get me wrong...you can sit your ass on the highway in the seat and get hit by a dump truck and walk away, but us big boys don't have all the options the 99 pounders do.
