Review on Stylish and Sporty: PUMA Boys' Core Logo Mesh Pant for Active Kids by Rob Dixon

My 10 year old son is tall and skinny. The perfect pant for him is Adidas adidas Big Boys Tricot Pant, Collegiate Navy, M . He has several Adidas pants, but I also decided to try on these Puma pants to expand our selection. Well, these pants don't have a drawstring, which doesn't make any sense to me at all. They are also larger at the waist than Adidas. Result? My son runs and these pants just fall off. I'm keeping them as he will grow into them next year and it's good to have thin slacks like these. However, I don't understand the logic behind making the pants larger than average and not including the drawstring.
