I bought this for my five-year old. For reference, he's about 44 inches tall and around 50lbs. The cape was full length but not so long that he stepped on it. It's made of that stretchy nylon material and has a velcro closure. The mask is heavy plastic and nicer quality than I was expecting - though a bit big for his little melon. However, it worked well for a Halloween costume and he and his siblings continue to play with it. Nice costume for a good price.
