HEROBIKER Thermal Underwear Boys' Super Soft Wool Lined Children's Warm Long John Top Bottom Warm Set (S-XL) Universal for boys and girls (Unisex version)

I loved the product. My daughter is 12 years old and the size fit perfectly. That made me happy, because buying online always involves uncertainty about the size, but in this case it worked out.

Very useful, we travelled to Canada in the winter, this thermal wears was a life saver as the weather was in the minus

I bought this set for my son and he loves them. The top and bottom fit, true to size, and he said that he was very warm. Thanks for a great product!!

It's really good. I got something similar in another shop for my daughter in November but I didn't know Walmart has much better quality . It's warmer and has perfect fitting. Highly recommend 👍

When I see kids without any layers on. Ankles sticking out , with low socks in winter . No undershirt. 🤦‍♀️ NO My son will. It wear pants without something tight on his leg, warm and toasty “The cold wind can't get through at recess”” or at the bus stop” he says Def size up. Always better to do that anyway. I did a medium this time for my 8 year old who's a tall, skinny Minnie, Def should have done large to have for next winter , bc he's growing like a weed ! Stay warm , keep your kids warm and healthy

Worked perfectly under my daughter's ski pants! Very soft and warm.

This was not a true thermal, and when worn under a sweatshirt , snowpants and a coat, we were still cold in 20° to go skiing in NY.

I ordered Small, large and Xlarge for my 3 kids. Xlarge did not fit my 16-18 child. Maybe i looked at the sizes wrong. Either way, theyre soft and the small and Large fit accordingly. Small fits size 6-7 and large fits 10-12

I have never owned wool lined clothing that you can see through. Yes the product is light weight but being able to see through the shirt and pants when you hold it up does not offer much warth or protection from the wind, you must layer this under something thick. Also you do need to measure and check sizes, my child fits between a L and XL ( bought an XL) abs the XL looks to be a L with no room for growth.

This is not what i asked for. This is cold athletics clothing. This is not thermal at all what so ever. This freezes you and does not maintain you warm. The cold breeze passes right through and you shiver.
