What is the max weight the Ecopass is suited for?
If you open the stroller specifications, we put the weight limit as well as many other specs in the different parts. The weight capacity of the Foppapedretti Ecopass (and most Foppapedretti strollers) is 15 kg.
It should be, however, able to carry a bit more if necessary. Don't put too much strain on it, though, to not make it wobbly or horrible to drive around.
