Bought these for my 11 y/o son, 4’9, 80-85lbs. He wears them every day to do farm chores, be in the woods, pretty much all of the time he’s outside. He’s sprayed them off after chores to clean them off and we’ve put them in the washer and hang dry, no problems. He’s quite slender and long legged. Thinking they won’t fit for a super long time. Probably should have gone up a size. Would be nice if the kids version had zippers too, but these are working well for him. They don’t bunch up too much at the top but don’t have a lot of spare room either.
