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. Over 60% of all hannas are certified by OEKO-TEX® Standard 100, which means they're tested down to the very last strand of thread for over 100 harmful substances, using strict European certification standards. We agree with the fan who said, "Oeko-Tex 100 equals 100 fewer things to worry about!" Our certification number is 03.U.9375 - FI Hohenstein.

Rated 5 out of 5 by Wonderful for layering Our boy likes to wear this under his long sleeves in the winter, they help him stay warm without having to have a think sweater on. They fit great on our daughter also, since it covers a little better than the girl version of this tank top. January 19, 2016
Rated 5 out of 5 by My son wants to wear these as regular tank tops He wore a tank undershirt today under a hooded thermal top -- and then wanted to strip out of the thermal when the weather warmed up a bit. Um, no. That's ok for home, but not at school. But, still, so soft and great as an under layer and so nice, thick, and soft. January 15, 2016
Rated 5 out of 5 by Difficult to find Our very cold winter calls for undershirt, my son loves this style, which is difficult to find, especially in such high quality cotton January 14, 2016
Rated 5 out of 5 by Boxer All three of my grandsons (3, 7 and 9 yrs.) LOVE these undershirts! In fact, the 3 year old wouldn't take his off for two days. He calls it his boxing shirt. These shrink a full size, so order the next size up from what you ordinarily get. January 12, 2016
Rated 5 out of 5 by Awesome Very good product! The best that I could find!I was looking everywhere for a long time. December 2, 2015

Rated 5 out of 5 by This tank is a must we bought this to go under her white button down shirt and she LOVES it!!! She wore it under and then said I want to wear it to bed PLEASE. So she did and now I must buy more! This is a great addition to the wardrobe...thinking other colors are a great idea too! September 22, 2015
Rated 2 out of 5 by white is see through This tank has great style and comfort. Unfortunately, the white was see-through, and hence I returned it. July 29, 2015
