Zeltbahn
Players are required to have at least one NVA Zeltbahn but are highly encouraged to have two, one to use as a poncho and one to use as a tent/rain fly
-These things work at keeping the rain off, as well as breaking
up your profile.
-They also double as a Strichtarn tent. (often called a shelter
half by sellers)
-highly recommend that you spray a waterproofing silicone on both
sides of the zeltbahn(s). This helps then shed water. The spray
can be picked up in most store's camping section.
