Cute shorts that have pockets and fit true to size. I love that they come in a pack of two as well. The black ones are my favorite and I feel like the fabric is a little softer on the black pair. The white ones are a little thinner than I would like. I was wearing an olive green colored underwear underneath them in the pictures in my review and though you can’t see them much, I do feel like they were slightly visible. The white pair also had a lot of loose strings on them which made me think the quality might not be as good as with the black pair. They washed easily and I hung them up to dry them because they smelled kind of funny when they arrived.

Good value for 2 shorts

These come vacuum sealed and have crazy wrinkles... so be prepared to do some ironing. I ordered the Mediums as I am a 6-8. The black pair feels a bit smaller than the beige pair... with both feeling tighter than I like for comfort. The look nice on, but feel like it constricts my belly a bit too much. Overall a nice basic set of shorts, perhaps size up for a more comfortable fit.

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.

Well made, light fabric. Waist doesn't roll.

These bamboo underwear really do keep you cool. They fit true to size, and wear easily. the wide elastic waist band doesn't roll on me. They are comfortable to wear, washed and dried easily. The material has some stretch to it, but not a lot. Well made, no stray strings. Perfect fit for me. Just what I was looking for.

Good quality, smooth feel

I got these briefs so recently that have washed just one pair so far. First off, these are very comfortable, the material is soft & bordering silky, good quality sewing. Wash well and minimal if any shrinkage. They do come a bit wrinkled from the dryer but hey, these are underwear and will go on smoothly. If it were a t-shirt, I would look sloppy. I feel the sizing is accurate. No rolling and these don't announce themselves under clothing. Planning on getting more of these boxers and replacing my old panties.
