By now you undoubtedly know the gist of the LZR: It's super-tight, made of a water-repellent fabric, and ultrasonically welded to remove any outside seams. But whether you think wearing one makes a swimmer a cheater or a resource-user, the suit does seem to improve times: More than 38 world records have fallen to athletes wearing the suit. Six versions of the suit will be available at retail shops, ranging from the High Neck Bodyskin, with full legs and more chest coverage, to the Jammer, which extends from the swimmer's waist to his knees.
