I had two baby carriers, so this one was used infrequently and is in good condition. It's a 2-way carrier that can be used for both front-carrying and back-carrying. It's very lightweight and easy to use. It folds up compactly, making it convenient to carry around. Would you like to use it as a sub-carrier, as it can be carried in a bag when going out? My home is pet-free and smoke-free.
