I got an Everdry 4 Drysuit also, probably at the same LDS as Freezerbrn. I recently dove in 55 degree water with some Harbor Patrol commercial divers wearing 7mm wetsuits on a night check out dive. They bailed out early because they were cold; I was nice and toasty.
As a matter of fact, I was so warm I am going to try it without the undergarmet that came with the suit. I strongly recommend taking the course because it is tricky to manage buoyancy control, especially when the air collects in your feet.
I did get some water in my suit on one dive, probably from air escaping out the neck seal. The LDS salesman told me to fold the neck seal over and tuck it next to my skin (like cuffing pants, but reversed). I don't think this is right, does anyone know? (Scubapro manual is moot on this point.)
