Review on Warm & Cozy ViCherub Boys' Thermal Underwear Set - Fleece Lined Long Johns for Kids - Ideal Base Layer Thermals - Pack of 2 Sets by Walter Day

I order small black two sets of underpants. I have 7 and 9 years old. Pants fit very well for both boys. I was worried I would have to order two sizes but the small one worked perfectly. Please note my boys are slim for their age. Pictured above is my 9 year old in his underpants. My 7 year old son is so picky when it comes to clothes and he told me they are so comfortable. Both boys refused to take them off and even wanted to put them on at night. They even played ninja. I had to argue with them to finally take them off because I wanted to wash them after wearing them for a few days :). We tested them on a winter hike and both guys were very warm. I need a pair for me!
