Mares 2nd Skin 1 5mm Shorty Wetsuit or something similar

[BRT]

I'd like a really thin shorty wetsuit with an attached hood. Probably 2mm max. Prefer something with a zipper rather than just a pull on vest. The Mares 2nd Skin 1 5mm Shorty Wetsuit seems like the right thing but they apparently don't sell it in the States and will not allow it to be shipped from other countries. That policy alone makes me want something other than a Mares. Any ideas?

Thanks
