Sabrina B. (5/5)

comfortable

"Quality fabric, I wish there was a bit more stretch but the fit is great nonetheless!"

Ingrid A. (5/5)

Good basic thong

"Comfortable thong, a but tight but colour is not for me so returned. Is quite a good thong but still prefer the Flex thongs."

Anna R. (4/5)

love

"Gorgeous as always. Fit very well and beautiful colour."

Georgia S. (5/5)

Great quality

"The quality is amazing! I ended up sizing up (small to medium) so these dug into my hips less, but it seems they are designed to, just a little bit, based on the model pictures."

Faye K. (5/5)

very comfortable

"love the gusset is larger than the average thongs ive seen and used"

Bilguun D. (5/5)

Love them but…

"I ordered all mediums to give it a try since all the reviews say they run small. Which is true but only for specific colors. Why does every color have its own sizing issue when it’s the same product? Black, white and tan run small (they do still fit but much tighter); grey, melon, and green fit perfectly."

Kacie W. (4/5)

Core thong

"LOVE the colors but they run small. Wish I would have gotten a bigger size."

Emily S. (3/5)

The hype is real! OB is the best!

"I am always on the hunt for sustainable, comfortable underwear and OB’s thongs are it for me. They are made of 100% cotton which I love. It makes them soft and breathable. I bought my usual size of M and the fit is perfect, even after washing/drying. These are the most comfortable thongs I’ve ever owned. I love them!!"

Deborah M. (5/5)

Great eco friendly option

"The cut is cute, but I prefer a high waist. These are cute and good quality."
