I got these for my son, who is slender. I wanted something that looked a little dressier than athletic pants but were still soft, and these fit the bill.I bought the size 6 slim for my tall thin 5 year old and they fit great. The ability to adjust the waist helps a lot. I love that they are comfy like sweatpants but look a lot nicer. He loves all the pockets!Very nice pants but they run small for a stockier kid.Bought for my 6 y.o. son. Fits great. Slim fit (not very easy to find)! It is thin and comfortable summer pants. Very happy.My son rly likes these pants. He doesn't like the stiffness of Jean's but likes the look of them, and likes these because of that. These are so soft and comfortable. I ordered his next size up to for when he grows.Nice for weekend comfy wear.These are the most comfortable pants I own! I wanted something other than sweats and these are it!FIT PERFECT!!!
