The Most Comfortable Panties You Can Wear


equestrian-no-panty-lines-250No Panty Lines - Total ComfortSmarty Pants women's underwear were designed to conquer problems of conventional underwear. Smarty Pants feature no visible panty lines without the discomfort of the thong. Wearing nothing under clothing is unhygienic, but Smarty Pants' exceedingly comfortable panties eliminate the need to compromise comfort and hygiene for appearance.

Smarty Pants underwear are lightweight, non-binding and anti-microbial. Flat lock stitching provides a durable, no bulk fit and the breathable gusset is double layered. Stylish Smarty Pants features a lower waist in a high performance, yet easy-to-care for fabric.

For Workout or Work, Move without Limits

  • sports or workout underwear that are comfortable in all positions
  • no more thighs rubbing together; no more chafing
  • comfy all day wear, unlike compression shorts
  • dancers: no more cutting off feet of tights
  • cyclists: reduce injury from falling with extra layer under cycling shorts
  • no risk of bladder or urinary tract infections as with the thong (see Your Health)

The fabric

Smarty Pants' unique technical fabric is super stretchy and actively wicks moisture away from the body to keep you dry and comfortable regardless of temperature. The specialized fabric resists odor, bacteria, fungus and mildew.

Machine wash cold, tumble or line dry: Smarty Pants dry in minutes (handy for camping or traveling).

Smarty Pants can be worn under:

  • workout wear
  • dancewear
  • yoga wear
  • cycling shorts
  • skirts and dresses
  • pants
  • ski pants
  • martial arts wear
  • equestrian/riding pants

Great for active and athletic women, but versatile enough to wear anywhere, anytime. At last, no more panty lines!


Fit should be comfortably snug, not constricting.
