Our 4 year old loves these. Great quality and he says they are breathable and comfortable. Washed a few times and they have good quality. Great value for money on these they are vibrant and stretchy.

My grandson is a Sonic fanatic. So I decided to get him these since he will become a big boy. He was so excited to have Sonic underwear on that it made potty training easy! Quality fabric and cute sonic designs.

I ordered these in a small and received a 4t I’m unsure what size I should be ordering because the information on sizing seems to be incorrect.

Nice product but completely wrong size. I ordered a medium, which by their sizing chart shows to be a size 8. The product I received says size 6, which would be a small. Very disappointing for the price!

I had to order this set twice as the first time I ordered a medium and was sent a SMALL instead. This time around I ordered a large and it fits my child as all his medium size underwear fits. Sizing doesn't seem accurate.
