Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!

Size: X-Large, Color: All Black D (5-pack)

Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

Ehh

Size: Medium, Color: Multicoloured E-(5-pack)

Very thin, still comfy but very thin material. Super soft though. I've worn and washed and they have held up but I won't be repurchasing bc these are so thin

They’re fantastic!!!!

Size: X-Large, Color: Multicoloured E-(5-pack)

My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.
