The wind and water-resistant Boys’ BIVY Down Hoody from Patagonia has the lightweight warmth they need for comfortable winter’s in the snow. It’s made from a durable polyester plain weave shell and liner, with contrast 4-ply nylon at hood and yoke for added protection. The jacket is treated with a durable water repellent finish, and insulated with recycled 600-fill-power duck and goose down for toasty warmth. It has a full-length zipper with a stand-up collar, external storm flap with metal snap closures for bundled warmth that protects against the elements. The adjustable drawcord hem retains warmth so they can stay out in the snow longer.
