Love these bamboo tops..I live in them!
Color: White, Size: Small
I am a fan of Pioneer Camp bamboo tops for their softness, natural fiber content and washability. They come out of the washer and a few minutes in the dryer looking like brand new. I have about 6 of the cropped tops and 3 of these longer yoga style for cooler weather. My daughter only wears natural fiber clothing and she asked me about the cropped tops because she really liked them; she now wears these tops and loves them, too, especially because she has a new baby and doesn’t want anything synthetic near her.
The fabric has a perfect ”weight” to it so that it isn’t see-through at all, but it’s breathable and so comfortable even in the hot Arizona summers.
I suppose the fact I have 9 of this brand top says it all..I basically live in them😊

Great shirt! Love the material! Super comfortable
Color: White, Size: X-Small, Color: White, Size: X-Small
I really love the material of the shirt. It is a very good quality. It is not too thin and not too thick. I think it’s perfect for when I am headed to the gym as well as I plan on just wearing it as a casual T-shirt. The quality is better than some of the high priced Alo items I have. I ordered an extra small and it is the perfect size. It is not meant to be fitted. So it is super comfortable. I would definitely order more colors. I also really like the back of it how it has the stitching in sections. I also plan on wearing this over a tank top for hikes on cooler days.

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.
