Family day on the sleds.

When the family is headed out for a day of snowmobiling, your son will want the Marmot Colossus Down Jacket to keep him warm and protected. Equipped with Marmot's 2-layer MemBrain technology, this jacket offers waterproof protection that can withstand snowing conditions on the sled and the heavyweight down insulation keeps him warm when dad picks up the speed. A detachable hood is available depending on conditions and is fully insulated to keep his ears just as warm. Micro-fleece lined internal cuffs are soft on his hands, and adjustable cuffs cinch out windy weather when his hands are out of his handwarmer pockets.

Love the down insulation. This Michigan winter has been brutally cold but the coat has kept my son warm. We intentionally bought a larger size so that we could get a few years out of it.
