Super comfortable! Great for layering under loose, cheeky shorts. Colors amazing!
Color: Multicolor B (5-pack), Size: Small
I specifically got these to wear under some loose shorts I got from Amazon (5 Pack Modal Lounge Shorts) so my cheeks don't show when bending over, and the pop of color looks amazing anyway! I have a 27" waist and 37.25" hips, and size Small works perfect for me. I love how these shorts have a classic underwear lining that a pad would sit perfectly on, whereas the longer boxer style ones of this same brand do not have that classic panty liner style crotch. The material is uniquely thick, stretchy, and thin/breezy all at once! To be honest, I am not opposed to wearing these straight up as shorts to work out it. They look like cute booty shorts and no one would know they're technically underwear. Plus when you buy a 5 pack like this, you're getting an amazing price whereas most athletic shorts are priced at $20 per pair or more, and they're not made with ANY natural materials like these BambooCool shorts are. I like them!

Best Sleep Shorts EVER ♥️
Color: Multicolor a (5-pack), Size: Medium
Love, love, LOVE these bamboo BoyShorts! I wear them for sleeping because they’re incredibly light, soft and comfortable while still having a great liner. They fit to my body while not feeling tight, snug or restrictive. Soooo comfortable. I’m 5’8” 145 lbs and went with Medium. ♥️

Amazing fit!!!
Color: Multicolor a (5-pack), Size: Large
These are quite literally the best underwear I have ever worn. I am going to replace all of my underwear with just these. I got the shorter boy shorts cut and they are amazing. These let my body be the shape that my body is, no squeezing or tight waist band. I feel so normal and comfortable in them, they’re breathable and soft!! I absolutely love them after so much trial and error with underwear I finally found the ones!

Highly recommend during pregnancy and to wear around the house!
Color: Multicolor a (5-pack), Size: X-Large
Love!! I’m currently 33 weeks pregnant. I’m 5’6” and pre pregnancy weight I would fluctuate between 132-140 lbs easily. I now weigh 162 lbs and my hip is now measuring 40 inches.
I bought the XL in the dark grey/black so that it wouldn’t be tight at all around my belly and I absolutely love them! Stretchy, comfortable, breathable. They aren’t loose around my thighs and I can tell they are gonna be nice to wear during post partum. I wear them around the house with an open robe and a bralette for the ultimate comfort.
If I were to buy them before pregnancy, I’m positive that a large would have fit beautifully, even though the small/medium measurements on the size chart would have been my pre pregnancy weight, I know they would have been too tight. I detest tight underwear!
Highly recommend!

Cute and Comfy
Color: Multicolor B (5-pack), Size: Medium
These are cute and comfy with a great fit. True to size they are cool and comfortable for everyday wear. I was going to order more but the price went up so I'm just waiting for it to go back down to order again.
