Napping is an essential ingredient in any successful Caribbean vacation, which is why island-bound slumber hounds should pack the 2.5-pound, football-size Hennessy Hammock. String the Hennessy between a pair of trees (preferably of the palm variety), step through the self-closing floor opening, and shaded, bug-free Z’s will quickly ensue. An integral ridgeline maintains the hammock’s curve, making it possible to sleep stably and comfortably on back, side, or stomach, all without the aid of a sleeping pad. Traveling with a special someone? Check out Hennessy’s two-person Safari Deluxe model. $119/$189. (888) 539-2930, www.hennessyhammock.com
