Strap in, Copernicus, it's time for a history lesson. The Double Delights are an ode to the “dilly dilly” name. For years, many have wondered, "What the heck does dilly dilly mean?" Wonder no more. It means an excellent example of a particular person or thing. With some super soft material and a spare beer pocket, this thing's the most delightful Hawaiian we have. Dilly dilly, my friends, dilly dilly.
