I agree with all the Maclaren recommendations. The Volo is their lightest model and like their other strollers, it can accommodate a child up to 55 lbs. which is impressive given how light it is. The Citi Mini is already pretty light vs. comparable strollers: other Baby Jogger, BOB, Valco, Bumbleride, etc. so Maclaren Volo is the way to go. You could always read the reviews on Amazon. That's what I do now before I buy anything--their reviews are great and some are very detailed.
