Anyone out there dive with 4th Element undergarments? My LDS is going to become a dealer for them & I'm curious at what people think of them. I'm looking at the heavier 2 pc. undergarments. Right now I dive a generic 300gm fleece undergarment & have had past trouble with the suit blocking the exhaust valve of my drysuit & also would like something a tad warmer, yet still flexible (I really hate the feeling of the kid in a "Christmas Story" when he can't move his arms). Any thoughts?
