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 Great absorbency and cmfort! This is the third set of Hanna training underwear I have bought and can only say they are great in every way. My two year old niece asks for " the soft pants!" Best recommendation in the world! May 18, 2016
Rated 5 out of 5 by Great undies for our 1,5 year old son Initially I intended to choose trainers for our son, which seemed better fitting around the legs but those turned to be very popular and not on stock. This was my second choice and they are great! Our son is toilet trained, undies are soft, great size for him (XS). Thank you for making high quality organic underwear for little ones! May 4, 2016
Rated 5 out of 5 by Great underwear So comfortable for my daughter. Made so well and chemical free. Love these! April 30, 2016
Rated 1 out of 5 by Fit too high and too gappy Very disappointed. They fit high on our 4 yr old and they're constantly gapping and open in the front. March 30, 2016
Rated 4 out of 5 by Well done!!! Our twin boys are tiny but getting ready for potty training. They are 2 and a half, 23 to 24 pounds and wear size 18 month clothes. I had hoped these would be small enough but alas they are still big. Given not nearly as big as the standard 2T that is the smallest you can find in a store! These did save me from having to figure out how to sew unders for my tinies!!!!!! Super soft and very well made! Pricy but well worth every penny!!!! Would recommend and will be buying more!!!

Rated 5 out of 5 by Not for Husky boys I have two boys with very different bodies. My skinny as a pencil son loves these and they are all he wants to wear. Unfortunately, my husky son can't even get into them. Because of this we've had to try lots of other brands. For those of you wondering what to get after they grow out of Hanna's, Jockey is not quite on par, but pretty high quality. Unfortunately, their boys sizes are hard to find. February 10, 2016
Rated 5 out of 5 by Beautiful Quality Briefs My 11-year loves his Hanna Andersson briefs. They are comfortable and fit him perfectly. He doesn't like patterns and the solid colour suits his pre-teen taste. November 12, 2015
Rated 5 out of 5 by Organic undies are the best So happy to find affordable organic undies at Hanna Andersen October 1, 2015
