Parents want to protect their child from sun and light, especially when it is sleeping. With the Joolz UV Sun hood your child is protected against sun and light. The UV Sun hood can be clicked on to the Joolz Day; the UV screen is invisible until you start using it. You unroll the UV screen and it becomes a full sunblind when you attach it at the rear end of the seat or the cot. A child can sleep comfortably without being disturbed by bright light. And, when (s)he awakes again, you roll up the UV screen and store it in the dedicated space in the UV Sun hood.
