Men's Viper X.3 Swimskin - Sleeveless
THIS SWIMSKIN IS DESIGNED FOR:
Elite speed + max freedom in non-wetsuit races—for athletes who prefer a sleeveless suit.
The Viper X.3 Sleeveless delivers front-pack, elite performance with more freedom than ever before. Patented IXI™ internal streamline support stabilizes your core and connects your hips to your shoulders—helping you stay streamlined and convert rotation into power and speed. Paired with an all-new ultralight, hyperflexible hydrophobic textile and seamless, laser-bonded construction, it's the freest, most comfortable version of our top-end Viper yet.
WHAT'S A SWIMSKIN? AND WHEN TO HAVE ONE.
Swimskins are used in warm water races (above 76.1°F / 24.5°C) when wetsuits aren’t legal. They reduce drag by covering your tri kit with an ultra fast, hydrophobic layer—and will save you several minutes in the water.
Because race-day water temps can swing by a few degrees, it’s smart to pack a swimskin for any race where water is expected to be over 70°F / 21°C.
