Yesterday, in the SE 27C heat, I see a few mums pushing buggies with something like this on their pushchairs. They are black, they totally surround the pushchair, and they don't look very breezy.
Am I the only one that think the LOs must feel hot and suffocating inside the darn thing? What's wrong with just a big canopy type shade, or a parasol? At least my DD is getting some breeze to cool down.
