Hamilton Stroller

Your best bet is to head down to the Hamilton showroom or service centre directly, they handle spare parts and replacements, so the sunproof cover should be something they can sort out for you. I've heard they do pop up at Takashimaya baby fairs with their full lineup too, so that could be a good chance to check in person and ask about replacement parts while you're there. Some mums I've spoken to say going direct to the brand is the most reliable route for this kind of thing, since third-party sellers may not carry the exact fit. Worth calling ahead just to confirm stock before you make the trip!
