An insulated sports bottle that keeps cold liquids colder more than twice as long as conventional bottles. It features a double wall construction with an insulating thermal layer in between that reflects the sun's heat away from the liquid inside. The screw on wide mouth top fits ice cubes and makes cleaning easier. It's dishwasher safe and the valve is removable for better cleaning. 24 oz capacity. Fits standard bicycle water bottle cages. BPA free. Wt.5.3 oz. Made in USA.
