## Description

desertcart.com: Rocky Thermal Underwear for Boys Cotton Knit Thermals Kids Base Layer Long John Pajamas Set (Black - Small) : Sports & Outdoors

Review: Very pleased, good purchase. - These are a lot like the cotton fitted pjs my kids like, but they are just a smidge thicker. I turned the sleeve inside out in my picture to show the material. I personally think they run true to size but if they lean either way it would be small. My son is a very skinny/small size 10 so the M is a little short on him and the L is a little loose in the waistband. Got the white ones for my son to wear Under his thin storm trooper Halloween costume. He likes them a lot and we are contemplating get a couple more pairs to wear as pjs. These are also going to be super convenient to wear under his clothes on snowy days. I’m completely satisfied with my purchase!
Review: Great price, great set! - This set was perfect for our son's costume this year. After reading some reviews, I ordered a size up (Medium) for our boy who normally wears a Small 5/6T. I wanted it a little lose not snug fit. It fits nicely in the waist and length on our tall ,lean boy. The material is good quality, color was bright and item just as described. Our son said is soft and comfy. Material is even softer after washing. Would definitely recommend for warm under clothing wear or pajamas!

### ⭐⭐⭐⭐⭐ Great boy’s Thermal Set!
*by F***F on November 10, 2020*

I purchased it for My 9 year old grandson, I got size large, it’s just a bit big in the waist, and the bottom is a bit long, but I expected that, he will grow into it. The medium would have been too small. He loves it. Good quality and nice feel against the skin. The waist band is not rough. I got two! Good stuff.
