A shuttlecock comprising at least a cap, a flared skirt having an inner and an outer part and an inflated device, for example a balloon incorporated in the space partially enclosed by the flared skirt, a plurality of stems form at least the main part of the inner skirt. The stems in the area of the inner skirt are substantially wider in a circumferential direction than the said stems are thick in a radial direction. The inflatable device is inflated to cause the flared skirt to swell so that a partially barrelled shape is formed in the inner skirt. A cirfcumferential member may be stretched to control the size of the barrelled portion. |
