Description

Soft, safe, and designed with comfort in mind.

These GOTS-certified 95% organic cotton briefs for boys are Oeko-Tex®100 certified, ensuring they’re free from harmful chemicals. The open fly design allows for natural air circulation, helping to keep sensitive skin cool and comfortable all day. The waistband is encased in fabric for comfort. Most waistbands on other brands of kids underwear are microfibre, a type of polyester.

We kept these basic in style to keep costs down for you. Basic black, and organic cotton with zero polyester and zero frills. Because our kids need safe, not fancy underwear.

More colours coming soon. 

Sizing note: Please choose carefully as we cannot accept returns on briefs and trunks. The sizing runs slightly large as they're designed with fast growing teens in mind.

Bought for my husband, who said “he didn’t feel he was wearing anything”, that is how comfortable he found them. Thank you.

These are seriously great undies. My Son loves them because they are so soft and fit super well. Caroline was really helpful too!

The fabric is soft and fits well. I bought these for my three sons and going a size up for each of their ages fits them well. Love it that it’s GOTS certified organic cotton.

Wonderful product but, not as soft as the boys trunks.

Great quality. These are a bit longer in the bottom so I sized down for my boys - They are usually size 8-10 but the 7/8 size in these undies fit best.

FAQ

Are these true to size?

Our Boys Briefs are a generous fit and we recommend sizing down if you are in between sizes.
Our Boys Trunks are usually preferred to be worn looser - so we recommend sizing up in these if you are between sizes.
Our Boys Skins are typically worn true to size.
