He seems to also like the vents on the sides of the stroller that might allow some more airflow. I like the shade seems a bit bigger providing a little more protection from the sun. But most of all, I love the front swivel wheel. I didn't realize how cumbersome the fixed front wheel of the other jogging stroller was until I walked with this one. We didn't walk far because it's HOT today. But we did give this a decent test ride. Nolan digs it.
