This 3D Camo Cover from Eastman Outfitters is made from a non reflective fabric with a Timber Illusion pattern.  If you don't want to use the standard camo tape, this is a great alternative, either wrap around your cache, or even glue it on, it will help keep your cache away from prying eyes and with the 3D effect it looks fantastic.

Designed by hunters to use to make hides etc, so you know it will do a good job.
