Barracuda - Thanks for the offer!
I have a hooded vest already and will most certinaly be wearing it! I am pretty sure it's a 3mm vest & hood (my son has a 3mm vest, with a 5mm hood attached, but it won't fit me) ...I've been thinking about picking up a 2 or 3mm bennie to layer with my hooded vest if my head gets cold. My biggest issue last spring when diving at temps in the low 40's was my feet... My boots have a bit more room in them than is ideal, but the next smaller size was too tight, so I am going to get a pair of neoprene socks to layer under my boots...
If I get really cold, maybe I'll take you up on your offer and layer vests too!!
