Whether they're riding in the carrier pack or toddling along snowy paths on their own, we're zipping them inside The North Face Reversible ThermoBall Hooded Jacket to keep them cozy on wintry treks. The treated material sheds flurries and drizzles, while the heat-trapping fill keeps them cozy even if it does get wet. When the winds pick up, we pull the hood over their beanie to give their ears and neck extra protection.
