"So comfy and high quality. I was expecting them to be the really thin and seamless ones that are cheaper feeling but they’re definitely not."
"The quality of the seamless underwear is great for activewear, and I like that they have a different range of colors to choose from as well so you can match it with the color of your bottoms. Good to get a combo of CSB leggings and their underwear in the same color. Take your usual size, it’s super stretchy and can wear it under your gym bottoms as the lining is mostly invisible."
"The quality of the seamless underwear is absolute perfection, and I like that they have a different range of colors to choose from as well. Take your usual size, it’s super stretchy and can wear it under your gym bottoms as the lining is mostly invisible."
"This thong is great for the gym, love that the material is made from bamboo; it looks and feels well made. You can barely see the lining through the leggings since it’s seamless. It definitely lessens the camel toe especially when wearing light leggings"
"Perfect to wear under tights or shorts"
"High quality and very comfortable for everyday use."
"This bamboo underwear looks so flattering on the buttocks. It adds this perfection form complimentary to the crunchy leggings. I’ve been browsing websites for a good pair that does not show cameltoe and this is the winner!"
"Really comfortable! Love that it doesn’t show when wearing activewear. Nice stretch as well, fits perfect also! Great quality."
"I have so many pairs of these now! Honestly the best under thights or for any tighter outfit. No lines"
"Best undies"
