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 One of A Kind You just can't get this fit or softness anywhere else! Love them. The designs are adorable too. June 2, 2016
Rated 5 out of 5 by Great fitting Training Unders Granddaughter will soon start potty training. What better than organic Unders? Daughter said the fit was perfect when she tried them on her. May 16, 2016
Rated 5 out of 5 by These trainers are MAGIC! All three patterns were so appealing to my first grandson, that he was totally on board to try to keep them dry. His four older sisters were just as excited for him to have his own BIG boy unders as they were with their own girlie Hannah trainers in the past. Thank you for one more great product! March 22, 2016
Rated 5 out of 5 by Best fit and comfort Cannot say enough about the comfort and absorbency and design. My two year old great niece who I purchased them for has some eczema and her skin is so sensitive and these have been just perfect. She says: " These big girl panties feel good!" (Best recommendation of all,) love every Hannah product I have purchased for many nieces and nephews. I always know that I am giving quality gifts! March 18, 2016
Rated 5 out of 5 by This garment surpassed my expectations! The size, perfect. The colors and designs, totally attractive and pleasing to my grandson. But most importantly, the quality and purpose are better than any other I have found on the market. Thank you for caring!! February 1, 2016
Rated 5 out of 5 by Best Fitting These are the best fitting underwear for little kids, hands down. End of story. January 18, 2016
Rated 4 out of 5 by Great trainers I like these undies a lot, but I wish they came one size smaller. Following Montessori's method of potty learning, we started when my daughter was 14 months, and these work, but they are pretty big around the legs, and that definitely makes for some leaks. With close fitting pants, less hits the floor, but I'd love if they could catch a whole one without the pants holding then on. That said, they are pretty much the cutest undies I've ever seen.

Rated 5 out of 5 by Love these organic training unders! My son just turned 3 and is mostly potty trained, but has some "uh oh" moments where he runs to the bathroom but a little wetness has already occurred. These are perfect for him. Soft comfortable organic undies that have a little extra absorbency compared to one layer underwear. They aren't waterproof, so if a full accident occurs, clothes will get wet. My son is 3, 32lbs and 36.5" (~50 percentile for weight, and ~20 percentile for height) and the XS fit him nicely. December 20, 2015
