You wouldn’t wear a regular bra during a speed workout, so why skimp on your bottoms? Specialty runderwear will keep you comfy and covered. These undies are so comfy they’ll make you want to streak—or umm shriek!
Athleta Free to Breathe Seamless Bikini
Stay cool as you work up a sweat with quick-wicking (but pretty) fabric.
Lululemon Light as Air Thong
Paper-thin, laser-cut fabric is the closest to commando you can get without going all the way.
Under Armour Pure Stretch Cheeky
Totally panty-line proof (even in capris!) thanks to an unfinished hem and snug fit.
Icebreaker Sprite Hot Pants
Naturally odor resistant merino wool is blended with Lycra for a baby-soft feel worth the splurge.
Champion Hipster Seamless Fit
Four-way stretch fabric moves with your stride—not up your booty!
Moving Comfort Workout Bikini
Breathable mesh stretches over the hips to add a little spice.
Asics ASX Thong
Never thought you’d wear a bright red thong while running? We didn’t either until we slipped on this seamless style.
