UPPAbaby Vista V2 is a tank, starting at 27 lbs with just one seat (more when leveraging expansion options). It's easy and smooth to move around, so you don't feel the weight while in use (unless pushing up a hill). The weight is noticeable when lifting in and out of a vehicle. For comparison, the BOB Rambler Jogging Stroller weighs in at just over 25 lbs..
