Patagonia Baby Reversible Puff-Ball Jacket. For winter newcomers intent on perfecting the faceplant, we offer the Reversible Puff-Ball Jacket. It blocks wind, moisture and cold temps with a fabric that’s soft and inviting, and reversible style that acclimates to surroundings quickly. The 100% recycled polyester ripstop shell fabric has a DWR (durable water repellent) finish to keep little bodies dry. The 100-g Thermogreen® insulation (90% recycled) holds in warmth even when wet. A 3-panel hood provides a close, comfortable fit; and the zipper garage staves off neck and chin chafe. The hood, cuffs and waist have shape-holding spandex binding, and the printed exterior reverses to contrasted quilt-lined side; on-seam pockets on printed side.
