Avoid criminal prosecution.
Don't send Junior out into the fight without the protection he needs. Suit him up in the Burton Boys' Fray Jacket. He'll stay warm and dry when he takes on the mountain thanks to a DryRide durashell and Thermacore insulation. It's that or send him out into the storm in a T-shirt and hope it toughens him up, but Child Services seems to frown on that.
The Fray's DryRide 2L Durashell laminate blocks moisture while remaining highly breathable so he'll stay dry when fresh stuff falls; the mini-twill face fabric with an environmentally friendly Aquapel DWR finish sheds the initial onslaught of moisture. Thermacore insulation (120g around the torso and 80g in the sleeves, hood, and collar) keeps his core toasty while giving his arms room to move
The expandable drop-down hood fits snugly over a helmet and then tightens down for windy chairlift rides, and the powder skirt with jacket-to-pants interface stops snow from flying up his jacket. There's plenty of pocket space including fleece-lined hand pocket, and a ported media pocket keep him organized, and glove loops ensure he won't lose his gloves in the lodge (again).
