The GB Zero is a light stroller with a very compact fold. The unique folding system allows the wheels to be folded inwards. In summer, you will appreciate the breathable mesh seat. There is an included seat liner for colder days. The non-reversible seat is fully reclinable and has an adjustable leg rest. With the purchase of an optional carrycot and/or a car seat, you can convert the Zero into any desired set, or you can buy a complete stroller system.
