Ordered a Lrg RB1 plus 4/3 to replace my RB2 which is a couple years old now and has a good sized hole in the calf area. The Lrg RB1 feels much smaller than my Lrg RB2 unfortunately. I’ve worn it twice now and it is just to tight. I’m 6’0 195-200 lbs. which is within the size lrg parameters. Bummed cuz my old RB2 fit great and I loved that suit. I may have to sell my new RB1 and buy a larger size now. Like I said my RB2 was a great suit and I’m sure the RB1 is too but it is much tighter than my old one. Shipping was quick and painless. I’d throw 5 stars at it if it fit better
