It seems like he was only in ski school yesterday, and now he's shredding powder deeper than you can handle, so get him some clothes worthy of his prowess, like the Marmot Boys' Vertical Pant. Unlike most youth ski pants, the Vertical Pant features the same protection that most of Marmot's adult apparel has. It has a waterproof breathable Membrain with fully taped seams to prevent a single snowflake from seeping through. Thermal R insulation equips the Vertical with welcoming warmth from fall to spring, and Marmot lined the pant in moisture wicking DriClime for a better performance. An articulated fit makes sure he can ski without this pant holding him back, and a grow system extends the cuffs so he can ski in this pant after he grows. There are stretchy boot gaiters with Cordura scuff guards protecting them.
