Review on LANBAOSI Kids Long Sleeve Compression Shirts and Pant Set: Superior Comfort and Performance by Paul Williams

You get what you pay for. I paid about $6 and in his first basketball game he slipped, got a big hole and scratched his knee on the court. They are nice to just wear, but not to play sports. My son is over 8 years old and 10-12 fits perfectly. Edit: I've found that it doesn't really matter which brand you buy, even expensive ones get holes in your knees. I ordered another pair for my (almost 10 year old) and ordered a size 12 thinking they should fit him. He is taller for his age and very skinny at the waist. Size 14 fits perfectly.
