Baby Jogger Summit X3 Double is a hybrid double stroller. It is a version of the Summit X3
for twins or siblings with a small age gap. The three wheels with air-filled tires are suitable for running as well as for everyday use. The X3 Double Summit can be reclined flat, which makes it suitable for one of the two or both children right from birth. By attaching one or two Compact carrycots, you can create a 2in1 stroller system. However, it is not possible to attach a car seat. All accessories, including bumper bars or snack trays, must be purchased separately. X3 Double is designed primarily for the Western market.
