"Underwhelming. The straps cut in which makes it clearly visible under tight clothes.. defeats the purpose. I’m normally a M in underwear but got a L in these.. they fit otherwise but the straps digging in means they won’t serve their intended purpose."

"Good"
Comfy Tstring
"The bamboo T-string from CSB in size M fits well on a 25. 5 inch waist and feels very comfortable to wear throughout the day. The bamboo fabric is soft, breathable, and doesn’t leave any tight imprints on the skin. It does run a bit small, so sizing up is recommended if you prefer a more relaxed fit. A great everyday essential."
