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 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
Rated 5 out of 5 by My son moves his cotton undies! So much more comfortable than his other underwear. August 23, 2015
Rated 5 out of 5 by Only Underwear My Sons Will Wear The soft cotton combined with the comfy integrated waistband make these undies the only ones my sons will wear. They once looked longingly at the superhero undies of their friends, but when they've tried those types, they've complained about the waistband and the fit. Both boys have very different builds-- one complains that his privates fall out of the leg of the other brands, the other complains that the legs are too tight on them. Now they only want their Hannas! August 20, 2015
Rated 5 out of 5 by We love Hanna I am so happy to have discovered this company. We live pretty remotely from any city and it's hard to find quality, organic threads. These undies are great and came in time for my little one's successful second week of being potty trained. They are a little large for his body right now and he will grow into them, but he is so pleased to be wearing new, big boy undies. Thanks for delivering our favorite quality clothes once again.
