hmmm it will likely be inaugural dives in my new Probe iDry 5mm fullsuit (plus iDry 5mm booties, frogskin hood, and gloves). I'll be working on a few eco diving courses, so hopefully I'll have to move around a lot and it shall keep me warm-er.I was sorely underdressed, with 2mm shorty over 3mm full wetsuit & 1mm hood. I should have brought my 5mm full wetsuit over 2mm shorty, which have served me well in Galápagos & Channel Islands down to 18-20C.
