Taking your eyes off the road to resecure your water bottle while riding your two-wheeler can be dangerous. Is a mouthful of water or XXX Vitamin Water worth running into the back of a Volvo? The Koala Bottle system is a safer way to consume some electrolytes while riding. The bottle magnetically attaches to the holster so you can effortlessly reach down and limit any fumbling around. The system is available with a 21 oz bottle or a 24 0z bottle ($2 more). It might be minimal, but your odds of hitting an open cab door just went down slightly.
