Hi Guys,
what mm are you guys using in Melbourne to snorkel? Mainly swim for fun and/or abs. Keen to extend the season and the time in the water. Used to dive a bit and had i think just a 3mm which was still cold most of the time....
Scuba shop tries to sell me a super thick wetsuit every time (more thick = more $) i am just a bit worried about being so buoyant and maybe ability to move freely diving for abs.
