MEN'S VIPER X2 SWIMSKIN

Meet the reimagined, better-than-ever Viper X2 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 IXI taping, silicone leg grippers, and premium performance fabrics—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 Swimskin is USAT and IRONMAN legal and continues to utilize two varieties of the same premium stretch-woven textile from Italy, a hydrophobic Teflon® coating, high-tech bonded seam construction with novel hidden stitch reinforcement and a low-profile autolocking YKK zipper. It is strategically designed with a pattern and panel layout that liberates your arms while providing support where you need it. All of these little details add up to free speed on race day. For the ultimate in swimskin performance, the ROKA Viper X2 promises unmatched support, technology and comfort.

IXI TAPING

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.

Reviews

Kona Ready

"I recently purchased this product for my 2027 Kona Legacy Slot and have just been advised that I've been moved to the 2026 event in October, so I'm super happy to have purchased ahead of time. Swimming is my Achillies when it comes to Tri and in Kona I realised it's a non-wetsuit swim, which is a challenge for a brick swimmer like me. I've had a couple of swims in it over the past week and the feel int the water is absolutely amazing. Time wise, I'm a little slower that with a wetsuit, but confidence wise, I'm absolutely stoked with the feel and swim times. Bring on Kona 2026 and Ali Drive."

— Dale C. (5/5)

Nice suit but not significantly faster than a Tri suit

"I raced the same course on multiple days at USAT Festival in Omaha. I tried it with a wetsuit, with this and with just my tri-suit. My overall times were roughly the same over 800m and 1mi with this vs. just my tri-suit. My wetsuit was, as expected, 15+ sec/ 100yd faster. It is an extremely well built suit but I am not sure it is worth the money."

— Tim B. (3/5)
