Rawlings Boys' Semi-Relaxed

Buenas Tardes, este precio es por los 5 pantalones?

My 10 year old wears a size 10 in pants. Would a large work for him? He is average to tall in height and average weight

My son is almost 7 and is short and slim.He typically wears a size 6 slim in jeans, what size would fit him best?

Is this for one pair of pants? The photo implies 5, bit I know that can’t be right.
