This thread is "ripe" for so many jokes.
If you had this problem with a 2nd brand only, then I might have suggested it might just be you, no offence.
But if you've had other suits since without the issue, then that raises an interesting question of why. Especially with others having the same problems with those brands. It must be something in the lining that is either causing a smell (off-gassing), is holding and concentrating the BO, or is causing mould/mildew.
I have not had this problem with wetsuits (xcel, ripcurl, patagonia), but the stench from booties can be so excessive that they need to be separately bagged to avoid stinking up the car. I don't pee in suits any more, so I can only assume the stench has to be from many hours of sweat pooling (because the suit doesn't flush with water enough while kiting vs surfing) plus mildew from never quite drying out. Yes, that is next level gross! And yes, it helps to have your partner also be a surfer/kiter.
