Even after a long day of skiing, Junior doesn't seem to slow down. So let him play in the backyard with Fido in the Hyperlight Down Jacket from Marmot, knowing that the 700-fill down will keep him warm while you warm up by the fire. While he's building snowforts and snowmen, the horizontal baffles trap heat and release perspiration so his body temperature will stay relatively regulated. And if the snow turns to sleet, adding a hardshell layer will keep him warm and dry while trapping all that snowman-building heat inside. After a day of play and a night of rest, the Polartec lined pockets keep those digits warm while he's waiting on the bus for better dexterity on that math or writing quiz later in the day.
