Elite's Crystal Ombra Water Bottle uses high quality K-resin material to ensure a crystal clear look. This material also has excellent anti-bacterial properties, making it one of the best for holding drinking fluids. Its oversized nozzle delivers fluid much faster than conventional designs and its cap is designed with a special blow-off feature. This means that it deforms when run over to help prevent crashes if it's dropped during a race or group ride. The Ombra bottle will fit any standard bottle cage, but has also been redesigned to mesh perfectly with Elite's range of bottle holders.
