these work perfectly permanently mounted to my F1 Mainframe Packs...
keep weapons or gear dry & lay flat when not needed, simple & effective!
Purchased this to use with the F1 frame and Vapor 5000 bag on an Alaska caribou hunt. It was a little difficult to mount it between the frame and bag as the attachment points are not great. It did protect my rifle well in the rain though. Once I was able to get it mounted securely, it worked as intended.
Great addition to add to main frame... water proof/dust proof ..and crown shield awesome also !
Got this to rework into a drag bag, but this would be an extremely useful piece of gear in it's original form. Plenty of material to form an adequate seal, even with a large rifle and optic. Impressed as always.
Will keep rifle dry and is light weight
