Love these

Love these panties!

Comfortable

I’m not a thong person, but I needed one for workout pants that were Lacey pretty high on the hip. These were comfortable, I was pleasantly surprised. I’m not an expert on them, but if you like them, you’ll love these!

Surprisingly great

Tbh, I’m not a thong person. I wanted to try these because they will go with the Lacey sides of the biker shorts and hide underwear. I’m surprised. These were very comfortable. If you wear thongs all the time, you would lik these.

Nice but fit is too small

Nice but fit small. Definitely would buy one size larger.

These run extremely small

These run extremely small. I’m between a medium and large and these were more like a small x-small.

Perfect for wearing under the white shorts!

Great workout thong

great fit and seamless - perfect paired with the Captivate shorts for a workout. I will note that I measure 28” waist and 41” hips and order my Captivate shorts in size small for a snug compressive fit but ordered this in a medium and I think a small would have been too snug for comfort. So I recommended ordering on the larger size if you are between sizes or overlapping on the size chart like I am!

Comfy

Perfect for working out.

Great fit!

Actually seamless

Finally! Underwear that’s actually seamless, stays put, is true to size, and is also breathable. I’ve tried so many different brands but these win by a long shot.
