The term "luxury liner" is normally used to describe cruise ships, but it has officially expanded its horizons to the undergarment world! OnGossamer's Luxury Liner Underwear ($19 each) are queens of the undies seas because they feature a high-tech wicking liner that wicks away moisture, keeping stains private. What's wicking, you ask? It's a fabric that moves sweat away from the skin to the outer surface of the fabric, where it evaporates. I can think of a few instances when this type of underwear will come in handy. It's available in thong, high rise, and bikini styles.
