Choosing between jacquard and bamboo viscose

  • Jacquard briefs are a nylon and spandex knit with a floral pattern woven in; they run from XXS to 5XL.
  • Bamboo viscose briefs are plain, stretchy and smooth under clothes; they run from XXS to 3XL.
  • Pack size is the real decision: three pairs cover a short cycle, five cover a week without a mid-week wash.
