My grandsonMy son is 10yrs old, very tall and thin, most his clothes I have to have drawstring in but these long Johns fix him perfectlyI bought these for my son for a cold weather camping trip and they did a great job keeping him warm the whole time, and they continue to be an awesome first layer under their clothes this winter. The only thing I'd fix is the neck hole-- it's a bit tight and hard to pull over his head so I just snipped the collar to make it easierI loved these for my 5 year old, and he loved them! The sleeves of the shirts fit kinda of snug that was my only issue. I got them not too long ago and the shirts are already getting too little for him and I’d have to rebuy again soon.Fits Well.Highly recommendedI love this for my son and its not the hard material its soft and my son loves itFits great under clothes
