This looks really great for rainy climates. Its made with three different materials and four colors to choose from. And i would consider it a very lightwright but durable rain jacket/pack cover.
I called it a system as it not only covers you and your pack. But it has many ootions as to how you can wear it. And how you can manage heat build up. I will let this excellent video review soeak to that in more detail. But this looks and sounds like an excellent rain management system.
