I waveski in this in 33-40 degree water up to six hours straight (never coming out):
Doesn't sound like you are half in/half out of the water the whole time like I am while waveskiing. You may do better with a 4/3 with a hood - enough for what you described as a quick swim to shore:
The "drylock" has Excel's new tech with more watertight seals in the wrists and ankle areas, as well as the zipper. Some folks don't like the "step in" through the neck/shoulder area design. I don't mind it. In which case, look at another brand like O'Neil, Rip Curl, etc.
I have a Kokatat and Palm drysuit that I have not worn in at least 5 years. Fact is, for me, the drysuits don't stay "dry" if I do anymore than lilly dipping. The wetsuits are far better, more comfy and, I would maintain, safer for my application which is waveski surfing on a rocky, barnicle covered break and/or reef. And, no, the wetsuit doesn't not hamper my paddling as some folks like to post -- which makes me think they don't have wetsuits and are just blowing smoke.
