Arctic HeroBoys' Thermal Underwear - 4 Piece Waffle Knit Top and Long John Set (Size: 2-18)

Bought 3T for my 3yo boy who is not particular large for age (about 28 lbs 36 inches), and these tiny for him. Will be returning. Now overall quality seemed just fine for a standard waffle style thermal. Since I didn’t get a 4T or bigger to compare not sure if we would size up one or two sizes.Bought a 2 pack of newer brand Brooklyn Vertical which seem to be much more appropriately sized (see attached comparison photos), so I’ll probably stick with that. I have absolutely no financial or other interest in either brand and haven’t received any gifts or items for free for a review or anything. If you can figure out right sizing I don’t see anything wrong with these and price is pretty good.

These were great as my toddler’s under layer when we spent a lot of time in the snow and outside in freezing temps. I purchased a size up from what my toddler actually wears, and I was glad I did. He typically wears 3T clothes. I purchased these in a size 4T, washed them before wearing, and they fit perfectly.

Returned, this pack of two items were nowhere near the same size. The white ones were sized correctly, but the black ones had a waist size that almost fit my waist and Im a small adult female. I unfortunately needed the back ones for my little boy's halloween costume, so I returned because I could not use them. If they were made correctly, as the white ones were, they would have been nice, but they were still pricey for the quality. I was also charged $2.50 at the UPS store to return, they made me pay for an envelope. Thats never happened before, so Im not sure about that, and its especially not cool since this item was defective.

Extremely disappointed! I ordered the pack of blue and gray kn 4t. The blue ones were 4t but the gray ones were 3t. The 4t are already really tight and I had to stretch them out around the ankles to get them on. There was a hole on the shoulder when I opened the package, and during the first night he slept in them, the crotch ripped. So both sets are useless and a waste of money. Horrible experience.

I bought size 12/14 for my average sized 9 year old and they shrunk to a size 8 and stretched out to be short and fat in the wash. They look ridiculous on my son but can't really return them now.

Bueno quiero aclarar que puse que queda como esperaba, por que por experiencia, al comprar la primera vez supe que tenía que comprar talla más grande para que le quedara a mi hijo. Ejemplo mi hijo tiene 3 años pero normalmente yo le pongo talla 5T en este caso le compré talla 7, el año pasado le compré talla 5/6. Y este año asumí que necesitaba una talla más grande y la talla 7 le quedó muy bien.

This product I got for my son (8 years old) was defective. The pants fit him fine, but the tops are for a 3 year old. I could see if both the pants and top were small, but for such a mismatch was a sad experience! Please look at the pics both of them say 12/14 and you can see the large disparity in the size.

I purchased charcoal and navy set for my son who just turned 4 last month. I purchased size 4, as one of review comment it fits her 4T boy. It indeed fit my boy very well, wasn't too long. However the quality doesn't seem very sturdy and thin. Charcoal material is more stiff than navy. I purchased it because we are heading up north west for vacation, but I don't think it will keep my son as warm as I would liked it to be. But will still keep it because my son likes it.
