I have been out on a few early Morning rides with this setup and I must say its quite good. Very comfortable fit and when combined with the Zephyr, its quite warm. We are still in early Springtime temps here in NJ...upper 40's in the morning and 70F on the ride home, so I havent really tried it in the heat yet.
I have recently added the Klim Ai-1 airbag vest to my kit and the stretch material that the Marakesh is made from has a nice "give" to it, thus giving the airbag room to deploy.
I do have one complaint...
I am 5'11" (180cm) tall and I have the size M jacket. When sitting on the bike the jacket "bunches" up because of its length and how it fits over the hips. If there were zippers on each side that would open up the base of the jacket this wouldn't happen. If you are a shorter rider , this would probably be even worse. I am considering taking the jacket to a shop to see if they could add the 2 zippers. Other than that its a super comfortable setup.
