Full coverage and full comfort
Size: XX-Large, Color: Multicoloured C (5-pack)
These boyshort underwear are a dream. They’re very soft, very stretchy, and very comfortable. They do not shrink when they’re washed. They’re heavy enough to make you feel like you have something covering you for discretion, but light enough to wear under any type of fabric. I have wide hips and I’m older so I don’t have a tight perky butt anymore. Most underwear tend to either ride up on me or become very uncomfortable. These stay where you put them. And they come all the way up to your waist so that there is no panty line whatsoever. The waist line is soft and comfortably. It does not dig in. They do not ride up and drive you crazy they stay where you put them. I would recommend them to anyone young or old. I have tried so many different styles and materials to find underwear that’s actually comfortable. These are the absolute best I have tried in five years. I just threw all the rest of them out.

Bamboo is an amazing fabric
Size: Large, Color: Multicoloured I (5-pack)
Comfy and soft . I’ve never worn boy shorts before so takes adjusting to. Legs roll sliding pants up but easy to adjust and smooth before zipping up then all day comfort. When I wear skirts or shorts they are perfect for that! I use to wear bike pants under skirts that don’t have to anymore. I like that they don’t creep up like regular underwear. I’m a new fan of bamboo fabric and bought briefs in bamboo as well.

The softest, stretchiest, perfect underwear!
Size: Large, Color: Multicoloured F (5-pack)
I have struggled for years to find underwear that didn't ride up. I like bamboo, but had the same problem with them. These Bamboo Cool Boyshorts not only solved my problem, but they are so soft and stretchy that it almost feels sensual pulling them on. They never ride up, roll down, they fit perfectly, and are always super comfortable. I even persuaded my husband to buy the men's version and he loves them too. And I should add, I never write reviews!

YES!
Size: Medium, Color: Multicoloured D (5-pack)
I don't give too many items 5 stars, but these are reorder worthy! I bought these a year ago, and am now going back for another 5 pack; not because my first order wore out, but because they are still SO great, I want more! These are my go to for under dresses, skirts, & flowy pants where I want full coverage, but no panty lines! AND bonus, sweat absorption. The leg openings are a tight when I first put them on, but they stay put and are very comfortable. I get my normal size

Comfortable but NOT SEAMLESS.
Size: Medium, Color: Multicoloured C (5-pack), Size: Medium, Color: Multicoloured C (5-pack)
They are soft and well-made, but they are definitely NOT SEAMLESS, which was my whole point in buying them. There are two cross-seams, as well as a fairly thick hem seam on the legs. If you have a problem with inner thigh or genital chafing, you may want to look at a different brand. Otherwise, these are comfortable and well made.
FYI, the ones I received had a matching inner liner, not a white one as some reviewers have noted.
