Trendy shaker for preparing all types of drinks used by athletes. The regular sieve has been replaced with a special BLENDER BALL made of a food-resistant surgical grade steel. The shaker is made of resistant and elegant colored plastic. The grip and the cap are lined with a layer of silicone rubber preventing the shaker from slipping out of your hand. Anatomic, narrow shape fits most drink bottle brackets mounted on bicycles or fitness equipment. Dishwashable.
