Kids Training Unders 3 Pack In Organic Cotton is rated 4.6 out of 5 by 92.
Rated 3 out of 5 by from good quality but small I bought three of this training undies for my daughter and I knew the hanna quality with organic softness, keep shapes after washes, etc, but as other reviewers mentioned before, the LEG HOLE! The waist and butt area looks right, but my daughter's thighs always so tightened and she couldn't take off the undies by herself because of the leg hole. It is miserable to see when kids are so ready and get right on the potty on time, but the undies never taken off and leaking.

Rated 5 out of 5 by from Great for potty training I am on Day 6 of potty training my two-year-old daughter and Hanna's training underwear has been instrumental in the process. I purchased 9 total pairs (wish I had gone for 12, especially for the first day of training!) and they are soft, absorbent, and cute. They have contained nearly all of my daughter's accidents. As other reviewers have stated, they can take an extra cycle in the dryer due to being 4-ply. I purchased XS and they fit my 34" tall, 27 lb daughter perfectly.

Rated 3 out of 5 by from Falling off my son My son is 26 months and 30 lbs so we bought the training underwear in size XS (80/90). We bought the 3 pack and two, 2-packs (Superman/Batman). While some of them fit great, keep accidents "in," and the material is soft and substantial, there are several pairs that literally fall off his body... he only has to take 5 steps and they are around his ankles (with pants off) or below his knees under his pants. I am pretty disappointed given the price and Hanna's usual quality.

Rated 5 out of 5 by from Fantastic product! I bought these because we are starting potty training and in my research a lot of people recommend these. They are fantastic! They are able to hold a lot! So I haven't had to worry about messes on the floor, which is so nice. They are a very soft cotton and fit comfortably. I bought the xs size and my 13 month old just barely meets the 20lb minimum so they are a little big, but other than that an awesome product!

Rated 5 out of 5 by from Excellent quality It seems that true high quality products are so rare, that I just had to write a review. These training undies are the best! We aren't training anymore, but the undies still fit and my daughter finds them comfortable, so she's still wearing them. She's a tall thin almost 4 year old and the XS are getting a bit tight, but the S still fit perfectly. I LOVE that they are organic cotton. Even more, I love that they have stood up to being washed on the extra-hot sanitary cycle many times, and they are still in perfect condition. The ones with prints even still have bright colors. We will buy another set of Hannas when she's outgrown these. Honestly, everything we've bought from Hanna Andersson has held up so well that we've passed on hand-me-downs to family and friends. As long as Hanna continues with the same quality, we are customers for life.

Rated 3 out of 5 by from Training unders The material is soft and the idea is great but they fit small in the waist while being big in the legs. My son does not like them.

Rated 4 out of 5 by from Very well made I bought a 3-pack of these at the Hanna Andersson outlet yesterday. Because of the way they were packaged I didn't realize they were trainers until I was tossing them into the wash. My 3 year old is totally out of diapers/pull ups but these are so nicely made I'm keeping them for winter use to keep her bottom extra warm when we play outside!

Rated 3 out of 5 by from Falling apart It makes me a bit sad to write this as I really wanted to love these. Had them shipped to the uk and everything. The cut of these are far better than everything here and my sister has used them for all her 3 kids and loved them. But we are a month in and they are falling apart. Noticed this morning that the threads are coming loose at the back and hanging down. The elastic around the waist has twisted too which is uncomfortable for my daughter. I emailed customer service this morning and am waiting for a reply but there is a time difference so may be a little while.
