having worn a lot of different suits for skin diving, surfing and scuba
2 piece open cell 5mm all year! on the (
3/ 35degree+days this summer) i only wear the top with board shorts!
come spring i will cut the "BIB" off my long johns.
stick well clear of all single piece "semi dry suits". they are a lavish way of saying "pox wet suit". they are good if they have a t-zip across the solders and cone seels on the wrists, ankles and neck.
but only for SCUBA!!!! too many air pockets in the underarms and crotch. making the free diver too buoyant.
if you get a rear zip up your back (surf suit) for freediving, i feel sorry for you!
too much cold flushing water!
