We are in the market for 5mm wetsuits & of course want to make the best choice possible. We really got stung with our Pinnacle Merino 3mms -- had to send them for seam repair after only a couple of years, & 3 dive trips later they are unravelling again (& we are careful divers who don't hit the coral!). Price is not an issue if we can get really good quality. We're looking for durability & stretchiness. Any comments will be really appreciated!
