Our pure organic cotton hannas are one way we can touch the future right now. Organics nurture kids sensitive skin with supersoft purity, while caring for farmers and our earth with non-toxic ecosystems. They're grown without chemical pesticides or fertilizers, and have no genetically modified organisms. Our commitment to organics is seven million supersoft-and-cozy pieces strong, and just like kids, it's growing every minute.


This is good for everybody.

Boys Unders 3 Pack In Organic Cotton is rated 4.8 out of 5 by 230.
Rated 5 out of 5 by from Just what I was looking for! I had been searching for good quality organic cotton underwear for my kids for a while. My son didn't love them at first because they are a little higher rise than his old underwear. However after a few wearings he loves them. I am glad they seem to be well constructed so will hold up for a while! I don't know if I would have purchased if I hadn't found them on sale. They are a bit pricey but we do love them.

Rated 3 out of 5 by from Please make a lower rise option! I love that these are organic and Oeko-Tex certified, but my little guy doesn't like that they come up to his belly button. He will still wear them, but they are not his first choice; he prefers lower-rise briefs from other brands, despite the fact that they all have the exposed elastic waistband. I LOVE the quality of the Hannas -- the prints are cute, they wash well and last forever -- and would gladly buy them exclusively if they came in a low rise option for boys.

Rated 3 out of 5 by from Way too large fitting These undies I am sure are very good, high quality like all Hanna items are. But, they were much too big on my granddaughter, and so loose fitting she would not wear them. Not fault of the undies, but, the size I ordered was what I thought was correct, but, they would not work. I recommend anyone be more careful with the sizing.

Rated 5 out of 5 by from Can't Say Enough Good Things About Hanna Unders! It's hard to spend that much on underwear for me, but I'll do it because it's so worth it. The softest, best quality underwear anywhere (my son wore his last set for two years and they look practically new still). And I love that they're organic too.

Rated 5 out of 5 by from Perfect comfort My son constantly reaches for these underwear first, because they are so soft. He loves that the waistband doesn't hurt his skin, and has just enough stretch. He also never complains of feeling constricted in these. Yes, the waist is a bit higher, but it is easily hidden below his normal waist jeans.

Rated 4 out of 5 by from Soft, but very high waisted My son is happy with these (he won't wear undies with exposed elastic) but they come up so high! He has a hard time keeping his pants up, so they definitely show quite a bit.

Rated 5 out of 5 by from Hanna unders Our kids have worn hanna underwear since they got out of diapers and now they're nine and eleven. We have tried other undies but again and again have come back to these. They are the best!

Rated 5 out of 5 by from The Most Comfortable My son doesn't say much about these, which is great! They are comfortable, good quality, and last!
