adidasBoys' Iconic Tricot Jogger Training Pants

Is there a draw string in the waist. My 12 yr old is skinny but has long legs & is 5'5 the XL may fit for length but might be too big in the waist

Are these more like sweatpants or track pants material?

Do these pants have a fleece lining?

What is the item number for the collegiate blue ? I’m trying to match w the jacket I have n it’s number 412
