Before he runs out the back door and into the woods, zip him up in the Tree Time Puffer Jacket by Columbia to be sure he stays warm while he plays with his friends. Water-resistant material keeps him dry as he runs through overgrown single tracks against wet bushes, while the synthetic insulation is breathable so he stays comfortably warm without overheating. When he starts racing the sun in order to get home before sunset, the adjustable hood will keep his ears warm against the evening chill, and the zippered hand pockets safely holds the new rocks for his collection.
