I bought two pair of these for my sons, age 6 and 9.  They had been begging for the expensive name brand versions of these and I didn't want to pay $40 for boys leggings.  I found these and tried them out.  They were thrilled with them and they fit TTS according to the recommended size chart.

One thing I deducted a start for-  they are very thin.  We do have one pair of the expensive brand ones we got on clearance and they are considerably thicker.  I make sure they are gentle when they  put these on because it seems like one slip and a finger could go through the material.
I will note that I do not put these in the dryer in hopes to prolong the life.

Overall, good for the price and my kids are happy.
