I see some semidrysuits online that people are claiming keep them warm at 40 farenheit. Are semi-drysuits good?
Do the hoods follow the same mm patterns as the wetsuits? Right now I have 2mm gloves.
Don't know, I pretty much use my drysuit unless I'm in a pool.
I know some people with them who like them, but no person experience with them. Remember the key to wetsuit is fit.
