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 Love them! These trainers are soft and I love the darker colors. I also like how they have a bit of boxy fit so they almost look like little shorts. I am going to buy some more as they are instrumental in my son's potty training. January 28, 2016
Rated 5 out of 5 by The product fits perfectly a very small 2 yr. old. I personally never see this product, but I do buy them for my grandson who is 2 and potty trained. He lives in Fla and I live in Va. But my daughter is extremely pleased with the pants.. Considering he is a small 2 yr. old, these pants fit perfectly. It's hard to find little tiny training underwear. And he has 12 pr from two orders. November 20, 2015
Rated 5 out of 5 by Perfect Perfect potty training panty!! Ordering another set October 3, 2015
Rated 5 out of 5 by Love these, but wish they made a smaller size I use these on my 14 month old son, and love the quality and that they are 100% cotton (no polyester!!), I only wish they made a smaller size. They are still much too large for him in the legs, and accidents can spill right out. For reference, my son is 32" inches and 24 pounds. September 28, 2015
Rated 5 out of 5 by Lovely Undies My girl is ECing and these work great. They are thicker in case there is an accident and they stay up great too. The only concern I have is that I wish they came smaller. She fits the XS size beautifully now at 13 months, but I would have liked to have gotten them when she was brand new and skipped the cloth diapers. Just like the undies for the bigger children, they are soft and I wish they also came in mama size. :) August 25, 2015
Rated 2 out of 5 by Runs really small Bought for grandson who just turned three, 40 in tall, 39 lbs. Bought size S, which is supposed to fit up to 48 lbs. Washed one time, cold water, and dried on low heat. The legs are too tight to pull all the way up. Lot of money to waste. Very much need to alter size chart, or make them to truly fit a toddler up to 48 lbs. August 5, 2015
Rated 5 out of 5 by A must for training I hope I can afford to buy all organic underwear for my kids. The organic cotton is very soft and the fabric is very thick. Contain the accident, so it won't wet the socks and shoes. Size XS for two and three year old. July 29, 2015
Rated 5 out of 5 by Training underwear These training unders are truly the best compared to other brands. Great quality, super soft material, and look comfortable! They hold up very well when accidents occur. I highly recommend!! June 27, 2015
