Quick Summary
The Mountain Warehouse Cannonball Kids 3 in 1 Waterproof Jacket is a bright blue kids coat in Teen Size 13 Years. It is described as a waterproof, breathable triclimate rain jacket with taped seams and a detachable hood, so the main buying checks are the size, the 3-in-1 format and whether the colour and fit are right for the child.
The jacket is stated as being wear-able three ways: the outer waterproof shell, the inner lightweight jacket, or both together for warmth. It also includes zipped pockets and a tricot lining.
