One thing to look for is a vent zipper on the back. I have a "First Gear" textile jacket and I love it. However, it has no rear vent zipper. Why is this important? Because the air needs to flow through the jacket. Otherwise 2 things happen. First, the jacket will tend to blowup like a ballon on the highway. No place for air to escape. Second, the airflow is critical for cooling. I use my textile jacket all summer and my leather jacket in the spring and fall.
