Insulated Sleeve for a 16oz Tumbler or Drink Holder are made with Insulbrite and quilted to help keep your drink cooler. The strap is adjustable and long enough to wear across the body to distribute the weight of the beverage and save your back and neck! My 16oz BPA Free tumbler is available for purchase for $9.00. The pockets are big enough for most cell phones, credit cards, drivers license, and a few dollars. Keys or a camera can be attached to a swivel hook.
