I have had the jacket only a few weeks now but on the 70° plus days it's been great. Went for a 200 mile ride yesterday in the 90's and I was more comfortable than if I had used my flannel. I wish it came in lighter colors, not just black. It still gets hot in the sun. Also the jacket kind of slides back down my back pulling the zipper into my neck which can be uncomfortable. I have not tested the waterproof liner yet but it seems legit and goes on and off the jacket well enough.
