Confusion over wetsuit thickness and layering

[lorien]

Be really careful about buying a one-piece and a core warmer for layering. Make sure that you always plan to use both together, and that you size them appropriately. If you buy a suit that fits, then try to add a core warmer under it, you will be back to difficult donning, and tight fit. If you buy a wetsuit large enough to fit comfortably over the warmer, then it will be loose if you ever try to use it without the warmer. I assume that a core warmer is designed to allow a wetsuit to slide over it, so binding shouldn't be a problem.

Another option is to buy the core warmer so you can wear it over your one piece suit. that is what I do and that wasy I can wear my one peice suit alone or with the core warmer. So far I have never been in a situation where I would even consider using the core warmer alone
