8.7kg is a great deal of weight. u need something lesser. there are alot of choices at affordable prices with lesser weight umbrella strollers.

i'm currently using peg perego pliko mini weighing around under 6kg. still quite heavy. my best friend just bought his chicco umbrella weighing in at 4.5kg. dunno how much or what model but i think he bought his when he was in japan.

every kg loss may not seem much, but it is a great deal of weight when travelling and for long hours/days.
