"The Elite line sets the standard in performance, comfort and style.  The Elite collection is comprised of sleek and luxurious triathlon essentials that will find a home in every triathlete’s wardrobe.  Crafted with dyed black premium Italian fabrics and trims, this collection is built for a high-performance, sophisticated look. 

The perfect cycling bib shorts for every ride, TT bike or road bike, from 1 hour to 8+ hours.  The bibs are made from a premium Italian fabric to allow exceptional freedom of movement, while the bib straps are constructed from a soft mesh material, with exceptional stretch for comfort.  Flatlock stitching ensures all seams lie completely flat to reduce chafing, and a 70mm wide leg gripper provides a flattering fit."
