Built to tackle everything from a stroll through the winter woods to hours of intense snowball fighting, the Canada Goose Boys' Rundle Down Bomber Jacket was designed with your little roughneck in mind.The outer layer of the Rundle Bomber jacket is a sturdy cotton/poly fabric that is coated with a washer-safe water-resistant treatment to hold the elements at bay. The jacket is lined with a smooth, durable nylon plain-weave fabric that's soft to the touch and won't cause irritation, even if it contacts bare skin. Of course, the real story is the insulation. Canada Goose uses high-quality 625 fill power white duck down. Down is extremely lightweight and packable, and locks in warmth as well as any insulation on the market. Canada Goose also filled the hood with white duck down for added head protection. The other feature that you'll love is Canada Goose's Gosling Graduate System, which allows you to extend the sleeves an inch and a half when the time comes.The Rundle Bomber also includes reflective piping on the opening cuff edges to make your child more visible, and a Goose I. D. hand-me-down label on the interior make the jacket easily identifiable and help trace the family history of the jacket. For added comfort, Canada Goose included rib-knit cuffs and waistband to seal out drafts. Finally, Canada Goose added two fleece-lined hand pockets, an interior zippered security pocket, and a zippered utility pocket on the right sleeve.
