Oh, yeah...I really don't like 7 mm suits either. I have a dry suit that I love, it's a Santi. The problem is needing a lot more weight with any dry suit, no matter what it's made out of, and that make it hard to do shore diving.
After trying on a few, I went with the
Seac Komodo 5mm. Awesome suit, they use some sort of unique "Yamomoto" neoprene made with limestone?? I don't know if that's for real, but I will tell you that it's very stretchy and comfortable, and incredibly warm. I was in my old Henderson Hyperflex 5 mm a week or two ago, and I was freezing after 20 minutes. With this suit, I could have stayed in the same water all day. Definitely a good thing to check out....
It does require a bit more weight (of course, that's why it's warm!), but certainly not the harness that I need with a single tank and dry suit. Between a weighted single tank adapter and an extra backplate, I was pretty close. Since I was diving shallow, I put a couple of trim weights in the cam pockets, but overall I'm very happy with the purchase.
