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.

Not what I’d hoped

Color: Multicolor a (5-pack), Size: Small

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.
