MEN'S Viper X2 Short Sleeve Swimskin

Meet the reimagined, better-than-ever Viper X2 Short Sleeve Swimskin, and wave goodbye to drag.

We weren’t satisfied with just creating the fastest, most popular swimskin on the planet, so we went back to the drawing board and upped our game. The result is the Viper X2, a swimskin that keeps everything you loved about the original—our patented ARMS UP™ technology, patented IXI taping, silicone leg grippers—and adds a new compression zone in the lower back that provides improved core support, promotes better posture and reduces drag by eliminating bubbling of the fabric in the small of your back.

The Viper X2 Short Sleeve is USAT and IRONMAN legal, and it fully covers your short sleeve tri suit on the swim to reduce friction and drag in the water. The suit is built with a premium Italian stretch-woven fabric and includes a hydrophobic Teflon coating, high-tech bonded seam construction with hidden-stitch reinforcement, as well as a low profile auto-locking YKK zipper.

FIT TIPS

  • Swimskins should fit snugly but comfortably without inhibiting your breathing or arm movement. Fit may feel different while swimming vs. on land, so make sure to try the suit in the water. They are meant to have a tight, compression fit, like a competition pool swimming suit.
  • Note that swimskins are meant to be worn on top of a race top/bottom or race suit only for the swim portion of the race. They are very specific, high performance garments not meant to be worn alone like traditional swimwear and the suits can be see-through under certain light or when wet. Undergarments such as a tri kit or swimsuit are strongly advised.
  • Your race kit will affect the fit slightly, so please be sure to try them on and swim in them with your race kit or another suit underneath.
Select your height, then locate your suggested size based on your weight.
