2XU Core Short Sleeved Trisuit Offering brilliant value and exceptional performance, the 2XU Core Short Sleeved Trisuit has all the features you need to excel during your target triathlon event. Just like its more expensive stable-mates, the Core Trisuit gets ergonomic panels to give a smooth and streamlined fit - that means fewer wrinkles and loose material to catch the wind and slow you down. Once you're deep into the efforts of your triathlon, the quick-wicking fabrics ensure sweat isn't hanging around too long, keeping you feeling cool and comfortable for the long haul. Across the lower body, flexible PWX material provides powerful muscle support, pushing back fatigue so you've got more to give as the finish line draws ever closer. Lastly, 2 side and 3 back mesh nutrition pockets keep your gels close to hand, easily accessible during the bike and swim legs.  TMF® Core Chamois An Italian seat pad designed specifically for the demands of short-course triathlon. The 65-density, 6mm medium-impact foam provides excellent on-the-saddle support for Sprint-distance tri events while the Skyve Technology removes unnecessary bulk to enhance flexibility during run and swim legs. A velour surface gives exceptional next-to-the-skin comfort and perforations improve moisture wicking.
