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.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.
