Who This Product May Suit
This jacket may suit a child who needs a single coat that can be worn in different ways across changing weather. The 3-in-1 format gives flexibility, while the waterproof shell and taped seams make the jacket relevant when staying dry matters.
Before You Decide
Confirm the 5-6y size and the Cobalt (01) colour before choosing an offer. If the 3-in-1 format matters, check whether you want the outer shell, the inner jacket, or both together for use. Review the 2,000 mm waterproof rating against the wet-weather protection you want.
