My favorite underwear
Size: Medium, Color: Multicoloured C (5-pack)
Super comfortable!! They are soft and breathable. No pinching, no shifting, and relatively invisible in skirts, pants, and loose dresses. True to size. Excellent quality, holds up well. Only thing is that the wording on the front does come off after a few washes, so you have to differentiate the front from the back of the underwear by how high the seam comes up. I almost exclusively wear this underwear now, I love it!

Incredible Comfort
Size: Large, Color: Multicoloured F (5-pack)
Amazing; I’ll be ordering more. Super soft, lightweight, smooth under clothes, incredible comfort! Best underwear! I ordered these because I’m tired of underwear lines when wearing biker shorts/leggings. Other boy shorts were too long or the bottom hem too thick and both of those issues left lines around my upper leg. THESE are *just right* - perfect length and fit. No panty lines on close fitting pants, comfortable under other pants and dresses, great with jumpsuits, and fit well under slip shorts with dresses.
NOTE: These take longer to dry, than similar clothes, in the dryer. No shrinking though.
SIZE: I ordered these in size L and they fit perfectly. A little snug when first on but they loosened up. For reference I’m 5’4” tall, about 175#, carry my weight in my hips and backside,wear size L sweats/pajamas/loose pants, size 12 jeans.

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!
