started out buying a lycra to ease entry onto my two-piece 7 mils. moved on to drysuits, so the 2 suits were sold/retired.
departed cooler waters for warmer waters. bought a 3mm suit. the lycra (above) was not enough to keep off the chills.
then either the 3mm suit shrank
ut: or i grew lumpier
so got me a larger sized 3mm.
all in all, 4 wetsuits, 1 drysuit (with two different undergarments but that's another tale
care for wetsuit - real rinsing as in dunking in a tub and agitating the water, leaving it there for about half an hour or so. i do use the wetsuit shampoo occasionally. oh, and used wax on the zipper every couple of dives.
when i sold my wetsuit, i showed how good the zippers still are, and the butt, knee and elbow areas, plus the fact that there's no visible evidence of collapsed cells.
