Thanks for the reply. I was hoping that it wouldn't make a huge difference. I can imagine that bowhunters and those who stalk turkey may have a bit more need for one.

Just to clarify, my pack is waterproof. I was thinking rain cover soley for the camo benefit. I may still pick one up if I can find it seperately and at a good price. It just seems like they only come as a set with a pack.
