Could do in a pinch, 'meh' quality
Size: Small, Color: Set-un8
Eh, I guess these are fine for the price. They're not super high quality, and the fit is kind of weird in my opinion. I have doubts that they would last a lot of repeat washings, especially the waistband. I returned them.

Love These
Size: Medium, Color: Off White/Rose Wood/Black
I am very sensitive to any kind of chemicals so I have to buy organic cotton fabrics. I have to wash anything I buy at least 5-10 times so I won't have a reaction. I only had to wash these about 5 times and had no reaction. I have a little muffin top, so I like the high waist. They fit really well, true to size. They are thin but well made. I will most likely buy again. I am 130lbs and 5'8"

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!
