I searched high and low for a comfy, breathable, affordable thong for kickboxing and exercising in.  This one really delivered in all categories!

Most of my other thongs, even the most comfy ones, could not hold up to the stretching and kicking involved in my workouts.  These really stood out in that they stay put, even if they get a little wedged are not as uncomfortable as other undies I've worn, are lightweight, but made of substantial, stretchy material.  They felt like they disappeared after I put them on.  I am a very happy customer and will be buying more of these for workouts as well as regular wear.

(I was a little disappointed about the thin blue line around the top of my taupe pair as I think it makes them look weirdly like an ace bandage, but it's a small price to pay for their undeniable comfort).
