Best! These are great for boys whose pants tend to sag. They fit well and are comfortable. August 16, 2014
The only underwear my boys will wear I've bought tons of underwear packs for my boys, only to be told, nope, not comfortable enough. Cheap underwear you buy has seams right where a boy doesn't want seams. I was getting desperate when I tried these, but they worked perfectly. They're so soft and comfortable and wash very well, though my older pairs are getting holes in them. My little one had a friend come over and after they played in water, I gave the other boy a pair of our Hannas and heard later from his mom that suddenly her son doesn't want to wear any other underwear. They're not cheap, and it sort of kills me to pay shipping on little boy briefs, but I'm happy we found them, and more importantly, so are they. August 11, 2014
Comfy and durable My son loves these! I buy him a dozen every year before school starts. I do find that the stitching on the waistband begins to unravel after a while, but they are still wearable. My son is rough with his clothes. My daughter wears the classic unders and we have never had the stitching come apart on those. I find these run a little small on both my kids. My son wears 130 or 140 in clothes, and he is moving from the medium to the large in unders this summer. August 8, 2014
Best Unders Ever! My mother bought both of my children these underwear when they started out in trainers. These underwear will last AND fit for at least 3 years, seriously, they do. These are the only unders they will wear and thats fine with me because they are so wonderful. August 5, 2014
Comfort, comfort, comfort My two boys are very sensitive to tags and stitching. When we found Hanna's Unders - we found the perfect product. The boys like the comfort (no more itching, scratching, poking). My younger son was especially adamant about no 'cartoon characters' on underwear. So, we love the choice of solid colors. Not only are they comfortable, but they wear a LONG time. We were able to hand-me-down from one child to the next. We hope that there is a young-adult version once they outgrow the XLG. July 22, 2014
Great fit These are great on my son. He has very sensitive skin, and these don't leave marks on his legs at all. July 21, 2014
Thank goodness for these! These are so classic and comfy! My daughter absolutely loves them! The only problem is proportion/sizing. I bought two packages, one for now and one for next year and the bigger size fits her best. She is tall and lean, so I was surprised the height/weght chart isn't necessarily true for this product. The leg holes seem a bit tight and the waist comes up much higher than I'd expect on a tall girl but she doesn't mind. July 12, 2014
My son has been wearing them for almost four years! My son loves these underwear. I bought my size small when he was just 18 months and he has been wearing the same size small since the fall of 2009 until the summer of 2014! They have been washed thousands of times and are still in perfect shape. The elastic is still strong and all the seams are in great condition. I just bought him the size medium. Definitely worth the investment. July 11, 2014
