What are cabana pants? Basically there light, comfortable pants that are meant to be worn in very casual settings. They are also meant to be worn in warm or hot weather, since they are thin and usually made of linen. Typically, they come in light colors like white, beige, or tan, and can be worn with sandals or with barefoot. perfect to wear on a relaxing evening at the cottage or the beach.
Two very nice examples, IMHO:
