The joey storage option is the ideal accessory for families who want convenience, longevity and relevance to suit their stroller to their lifestyle. The joey clip-on tote bag easily transforms the right side of the Mountain Buggy duet stroller to a single buggy with loads of storage, making this the perfect convertible for first-time parents. The sturdy frame easily clips into the buggy and includes two tote bags that nestle inside. The joey option is also compatible with the new carrycot plus and with an infant car seat on the other side.
