Elastic Soft Waistband
kid’s long underwear is ultra-comfortable. That’s why the elastic soft, slim fit of the waistband provides comfortable and chafe-free wear all day
Nature will come calling. Kid’s thermal underwear provide a fly/pee hole for an easier way to answer nature’s call without having to get undressed.
Stretchable & Lightweight
The fabric is lightweight so as not to weigh your kids down. They’ll enjoy full-mobility with no movement restriction with the four-way stretchable fabric.
Shipping & Return
I loved the material and the sizing of this underwear set. They're warm and comfy!
They were well made, comfy and super warm. My son is 8 and we purchased the medium. It was a perfect fit. Definitely will order the next size up for next winter.
I got the M for my 9 years old son. He is petite/thin and these fit great(not tight but fitted enough to be a good base layer).
The fabric was lightweight but substantial which was exactly what I was looking for.
The fit was perfect and he was warm and comfortable. I highly recommend them and will be ordering Thermajohn's again.
