Comfy but holes.
Size: Large, Color: A-multicolor(6 Pack)
Comfy and cute - holes and falling apart already. Im not sure if I just got a bad batch/pair, but the seam at the crotch connecting to the "gusset" is detaching in the black one... I really liked them too. Only worn them like 2 or 3 times, so now im worried about wearing the others.

Not full coverage
Size: Medium, Color: A-multicolor(6 Pack)
These are not full coverage and are the cheapest underwear in every way. The fabric is rough, and the seams around the edges of the leg openings are exposed. I ordered medium for my 28" waist and 38" hips. They fit... except for the buttcheek debut. I gave them to my 12 year old daughter to wear because she's not picky. Plus, they were cheap. She's happy. I'm still searching for full coverage undies.
Update: The seller reached out regarding my review, and I'm impressed with their customer service. The cotton softened up upon washing and drying (no sand paper undies), and my daughter is very pleased with them.

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.
