The fabric is nice, soft without being overly bulky. The design was almost what I wanted. I’ve been trying to find underwear that won’t ride up and is comfortable to wear under leggings. The fabric has a LOT of stretch around the legs and deforms quickly. Then it rides up and wrinkles. Smaller leg openings might make the difference.

Great & Comfortable

Color: Multicolor B (5-pack), Size: X-Large, Color: Multicolor B (5-pack), Size: X-Large

I have bought 2 packs of this underwear. I love wearing them. They are very comfortable, and the size fits perfectly. I like most of the colors. The Bamboo Cool lettering on the front does come off after washing though. Otherwise the underwear has been great to wear.

Better than woxer imo

Color: Multicolor B (5-pack), Size: Large

I've been buying Woxers, but theyre super expensive for what youre getting. These are similar in feel and style so i switched over. Another nice thing is i dont have to deal with wedgies like i do with the woxers. Theyre not perfect for wearing when its hot, youre still gunna sweat and these dont wick away sweat super well. But i havent seen many brands that do, and these are not the worst. Im 5'7" and 145lbs and these are comfy and tight enough but not snug. They still leave a bit of indentation on the love handles. You CAN tell that youre wearing them under pant if they are tight.

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.
