"The Patagonia Down Sweater Vest keeps core warmth accessible for kids without the bulk of a full jacket. Reclaimed down insulates through cool mornings and breezy trail days, and the NetPlus recycled nylon ripstop shell holds up to the kind of daily use kids put gear through. What Our Gearhead® Experts Are Saying:""Stuffed into its own chest pocket, this vest packs down small enough to live in a daypack or backpack all season without taking up real estate."""
