The Swiss Alpenflage happens when women are let into the army and camouflage starts to menstruate. Or so we heard. These are cut only as a poncho, and cannot really be used as improvised shelter. Then again, for a poncho, these do the job better than others.
Material is rubber impregnated polyester or nylon. No Gore-Tex on these! Waterproof. Real proof.
Used, perferctly usable Swiss quality.
