A cooler cover is disclosed herein. The cooler cover includes a first layer constructed of an insulating material, a second layer constructing of an ultraviolet ray reflecting material attached to the first layer, and at least one handle-aperture passing through the first and second layers. The first and second layers may be quilted together to form a single cover configured to enclose a cooler. The cooler cover is useful for protecting a cooler and its contents from UV radiation and thermal transfer.
