THE STROLLER The YPSI measures just 20 inches / 50.8 cm wide, perfect for adventures where space is at a premium. The streamlined design of the chassis makes manoeuvring through crowds easier and more convenient. The telescoping handle accommodates users of different heights and the hand-sewn eco-leather bar adds a touch of elegance.
