Really comfortable, good fit
Size: 6X-Large, Color: 5 Pack(black,black,blue,blue,light Coffee)
These are very lightweight and comfortable. The material stretches freely and doesn't bind up anywhere. If you go by the size guide, they should fit perfectly neither too loose nor too tight. Would definitely recommend.

These don't work for me...
Size: Medium, Color: B005
First the good... I like the material; it's very soft, light, and stretchy. I also like the colors, but that's all I like about these boyshort panties. My main goal for panties is to have them NOT ride up into my butt crack leaving the bottoms of my butt hanging out. It's probably comfortable for some, but it drives me nuts to feel this constant need to pull them out of my butt crack and down over my butt cheeks. If I wanted my butt hanging out I'd buy thongs, LOL. The part I really don't understand, is why they make the front and the back the same width/length. I mean clearly more material would be needed in the back to fit around two round humps, right? I mean I guess unless you have what I call a pancake butt, I don't see why there shouldn't be more material on the backside of the underwear. Why is it so dang difficult to find underwear in this style to fit up over butt cheeks? If I pull them down enough to cover the bottoms of my cheeks then the waistband is sitting right at the top of my crack which is extremely annoying (then I feel this constant need to pull them up!) especially when the front is long enough to go up to my belly button!! Who are they making these underwear for??? Ladies with FLAT butts apparently. For reference, I'm 5'5" 130 lbs, hips 37", waist 27", athletic build, as in lean but with muscular glutes & quads from speed skating. Not only are they not made big enough to go up over my rump while still keeping my cheek bottoms from hanging out, but they're too long in the front cause they constantly roll up in the front. I've even tried turning them around, even though they seem to be exactly the same front to back, and they fit exactly the same, no surprise there. I may just be out of luck finding comfy boyshort panties that actually fit the way I want them to. :/

Comfy and well made

Love these! They stay in place, are soft and comfortable with just enough stretch but hold their shape. This is my 3rd order.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
