I live in livermore and I am always looking for people to dive with. Count me in.
I have a mares flexa 8.6.5 and a 7mm hooded vest and I have had no problem with the cold. So far i've been in the water for almost 2 hours. After 50 mins diving, stayed in the water for another hour hanging out with the seal that decided to join us, and never noticed the cold. This suit has really good seals with almost no flushing, so for the time being, I am not interested in looking for a drysuit. I dont think I could handle the weight of 2 tanks either.
