Reviews

So Comfortable!

"I absolutely love these! I did exchange them for a smaller size, as they were a little too loose for me, but once I received the new smaller size, I was in love! These are so comfortable and I actually wore these with jeans and they didn't feel uncomfortable. I also wore these as shorts to bed and they were so comfortable for sleeping. Definitely getting them in more colors!"

— Jillian Z. (5/5)

I love the ribbed fabric

"I love the ribbed fabric and the shape and the variety of colours - but they dont stay put over the bottom (so little elastic here!) so they still dont fulfil my desire for the perfect pants! The hunt goes on . . ."

My favorite OB underwear

"These Core Rib Shorties are my favorite! They are super comfortable and feel like there's less elastane than in the non-ribbed type, something I really hate in my clothes. Unfortunately with underwear, it's impossible to find any without elastane, so these are the best. I wish Organic Basics would make these in more colors to match all my bras and in a lower waist version. Shipping was fast and secure, as always everything was great!"

My fav undies

"I love these shorties so much! I own over 20 pairs."

— Jessica E. (5/5)

Nice, maybe size down?

"Nice quality, comfortable to wear. I was hoping the fuller coverage of this style may prevent shifting, but I found they do unless you're wearing them with something tight fitting. It may be because of the fiber content, mostly cotton, so I wonder if it sizing down would help with that."

— Heather H. (5/5)

Favorite sleep undies!

"I love this cut and sleep in them every night. They are my preferred lounging pair. So soft, and good for your biome. Highly recommend!"
