That's a good review of the products.
I've only used the Thermolution so can only attest to that product. I would agree with everything the guy said in the review...and his comments about other products tested reflect comments I've heard from other people who have tried them.
Also, I believe Thermolution is coming out with a new & improved switch...should be available in the next month or so?
As I said in another related thread...it's hard not to love the warm boost the suit can provide on those cold days if you're trying to extend a good session without being miserably cold. I'm glad to hear I'm not the only one who likes being warm in cold water
And, If you are a scuba diver Thermolution also has a deep water rated suit,
