Swimming the Bering Strait this winter?

This is an XL Body Glove cold water three piece wetsuit. It is BARELY used, and in like new condition.
How thick is it? Way thick....5 or 7mm? I tried it on once and could hardly move in it, much less swim, much less surf.
Its probably great for diving, say,..the Mariano Trench.
It was initially purchased to wear while cleaning boat bottoms, but never used by us.
$150 should do it.

I'm told this is a "Body Glove X2" of 5 or 7mm.

And it is a two piece, not three.
The hood part must have been sold seperately.
