High rise The rise on these underwear is way too high. My son found it uncomfortable and he looked like he was wearing old man pants! Too bad,the fabric and seaming are soft and high quality. We will be returning these. February 8, 2015
Comfortable and well fitting My son loves these and so do I. They are the correct size and the fit is perfect. February 7, 2015
Comfy and Cute My little guy loves his unders. They are comfortable and the designs are fun. February 3, 2015
No more plummer's crack! These are so much better than the underwear my son had before, which always gave him plummer's crack. I love that the elastic waistband is covered in cloth, which seems to make the underwear easier for him to pull up. These are soft and stylish and fit perfectly. January 19, 2015
simple and perfect These are the only underwear that we buy for our son. He has a slender build and they fit perfectly, are completely fabric (no exposed elastic waist band), and are just a simple, perfect pair of underwear. He has worn the same size for over a year now, and though he has grown in that time (and outgrown most of last year's clothing), the underwear seem to fit just as well now as they did when we first got them. We recently bought a new set to be sure that we would never run out when traveling, and the quality and construction seem the same. I imagine we will be buying these for many years to come as he continues to grow. September 18, 2014
Just what we were looking for I am glad we purchased the medium briefs over the small ones. Our 4 yo is about 48 lbs and the medium briefs fit well now with a bit of room to grow. Soft material. Vibrant color/patterns. I will order more! September 1, 2014
Best underwear ever I wish I could afford to buy more, will wait till a sale. Much better quality than the bikini underwear you find at big-name stores. Much better coverage, too. Does sit high on the waist, if this matters to you. But it looks so cute on the kids!! August 25, 2014
Our go to underwear! My daughters will only wear Hanna underwear so when it came time to potty train my son, I knew where to buy his "big boy underwear." Yes, they are pricey, but life is too short to wear uncomfortable underwear. We are able to hand them down to siblings and cousins so the price is worth it. We don't even consider any other brands. I think these run a tad small, especially if you are buying them for a toddler that still has a bit of baby chubbiness. I bought the 100/110 and they just fit my 3 year old. If you have a lanky boy, it shouldn't be a problem, anyone else might want to size up. August 6, 2014
