If you’re a good-to-excellent swimmer looking for a bit of warmth or buoyancy, the maximum 3mm of neoprene will work fine; if you’re a poor swimmer hoping to float those anchor legs of yours, keep shopping. The huge upside of a very thin wetsuit like the Rocket Science Sports One — aside from price—is the high level of flexibility and range of motion in the arms. In terms of restriction this suit feels more like something made of high-end rubber in the $300-400 range. With that said, the thinness is nearly on par with many speedsuits.
