Reason I ask this is because I am considering the Klim Overland gear and they do not have a zipper that will allow the Jacket and pants to zip together. I have always owned gear that had a zipper on the Jacket and pants allowing them to zip together which is supposed to keep the jacket from riding up your back in a get off. I have never tested that theory but it just seems to make sense. I am trying to justify the Klim Overland because of the price point but don't want to make a mistake and wish I had gear like the Laditude that would zip together. What is you opinion on Jacket and pants zipping together? Is it a must..
