The Hauck Viper SLX is a newer version of the original Viper. It is a three-wheel stroller with a chassis with larger foam wheels, which are somewhat less robust and have lighter rims. The non-reversible seat with a high weight capacity can handle even a bigger child. It is fully reclinable, suitable even for the smaller ones. The large shopping basket is also accessible when the seat is reclined, thanks to the unzippable part. You will no longer find any side windows on the extendable hood. The stroller is either sold separately, in a travel system with a car seat (Hauck Viper SLX Shop´n Drive), in a 2in1 stroller system with a carrycot (Hauck Viper SLX Duo Set) or, most commonly, in a 3in1 stroller system with a carrycot and a car seat Hauck Viper SLX Trio Set.
