Best thong I’ve ever had
This is by far the best thong I’ve ever purchased it fits perfectly, good for all day wear or going to the gym. I wish they would make a jock version of this exact thong the duel tech jock/thong doesn’t fit as well as this one it’s very tight in the front. I’ll definitely be ordering more soon
