The Silver Cross Jet stroller can now be purchased in the US.

Jet is an all-new, ultra-compact, lightweight travel stroller system that folds as small as cabin baggage (and meets all major airline size regulations) and wheels like a small suitcase. Jet is suitable from birth up to 40 lbs and despite its small size, it is roomy, durable and sturdy like a full-size stroller. It can also be used as a travel system with compatible adapters.

Right now it is sold in 4 colors.
