I am still using a hyperflexx 4/3, a little warm but since I don't have a 3/2, it gets me by. I get the same chaffing really bad, all you need to do is coat your neck with body glide, takes care of the chaffing no problem.
Yeah.. I hear about that or vaseline.... i hate putting stuff like that.. but it gets to a point where my sessions are cut a little short! im a ***** i know... bout to cut the **** off.
A wetsuit shouldn't make you that crazed, dude. Yah, some of the wetsuit executions of the designs suck ass & irritate the neck. IMHO....slather the bodyglide or pig's grease or whatever on that rubber & just surf & be glad that you're in the ocean, 'cause it's a gift. And maybe go get laid? Sounds like you're backed up. Things sound tense over there.
honestly put a piece of duct tape over the seam that is bothering you. I wouldn't use Vasoline or anything that could eat the rubber. You could also try putting a piece of duct tape on your NECK which would probably work better.
vaseline kills suits, don't use it. ever since i have been getting suits with the slickskin material on the collar, i haven't had this problem.
I have the same problem with my back zip suits. My nicer chest zips are no problem cause they have nice collars but the back zips rub my neck pretty raw. I just deal with it but I've been doing a little research lately and found this thing called Necktech. I'm thinking about getting one to try out, here's the link: http://andrewswatersports.com/necktech/
i always wear underarmour under my suit. but its a lil warm for a suit now...they make a "summer" under armour that works well
