The Hamax Rain Cover is specially designed to preserve and protect your Hamax child bike seat when not in use. Heavy-duty, nylon material is water-resistant and features an elastic band to fit securely and snugly around your bike seat to keep out moisture, dust, and grime. Take it with you on the go to keep the seat dry between uses on a rainy day. Protect your Hamax seat between seasons when stored in a garage, closet or attic.
