THIS SWIMSKIN IS DESIGNED FOR:
Max speed—witore freedom and comfort than ever before.
The Viper X.3 Short Sleeve is our fastest, most technically advanced swimskin. Its elbow-length sleeves deliver maximum coverage—and maximum drag reduction—especially for athletes racing in sleeved tri kits.
What sets it apart? Patented ARMS-UP™ construction paired with an all-new hyperflexible, hydrophobic textile that offers unmatched shoulder freedom in a short-sleeve design. Inside, patented IXI™ internal streamline support connects your hips to your shoulders, helping you hold a tight body line and convert rotation into forward speed.
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 a slick, 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.
