Named after the advanced fabric from Eschler of Switzerland, the high-compression fit provides incredible muscle support and the dimpled surface streamlines your movement through the water and air by reducing drag over its surface. Plus, the sleeveless design and mesh side panels contribute an amazingly light feel and the shorts include a comfortable and moisture-wicking fleece pad. This speedy piece has a hidden zipper and 2 easy-access rear pockets, too. - Aero-XT, improved for 2008, has superior aero & hydrodynamics, advanced muscle compression and is faster drying - Cut cross-grain creates high compression fit - D-Vente mesh side panels - D-Vente bra liner - Two back pockets placed for speed and access - Durable, but soft and light, fleece chamois - Contoured flat-seam construction with gusset - 14-inch zipper on back - Available in Black Only. AERO-XT is a unique fabric that is highly aero/hydrodynamic thanks to the highly textured and unique interior. The 86% micro-denier Nylon and 14% Spandex is an effective blend that allows for a soft hand, a great fit and quick drying. The "high-amplitude" structure of the interior creates "low-amplitude" dimples on teh surface, allowing the right amount of turbulence across the fabric surface, thus lowering drag. This structure also facilitates evaporation. D-VENTE is a Polyester/Spandex micro-denier mesh that delivers an uncanny equilibrium between the input and output of heat and moisture. Whether hot or cold outside, D-Vente helps maintain a constant body temperature and superior moisture control while delivering a great body-hugging fit.
