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 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
Rated 5 out of 5 by excellent quality We love the Hanna Andersson quality of clothing, especially the underwear holds up well after many washes. Well worth it! October 1, 2015
Rated 5 out of 5 by The ONLY underwear My son has been wearing Hanna underwear since he started in a Small. He is now in XL and I do not know what to do when those do not fit! These underwear wash and wear so well. They are the only underwear he will wear, especially due to his eczema and tactile sensitivities. These underwear are worth every penny. Can Hanna please start making XXL in boys' underwear? September 30, 2015
Rated 5 out of 5 by Great for picky son My son is very particular about the feel of his clothing. These are very soft and pretty much the only brand that has a waist band with the soft cotton covering the elastic waist band. He loves them. He is now in an XL, don't know what he's going to do when he gets older. Any suggestions, anyone? August 30, 2015
