I belive they bought gameplan gear a while back. This is the same pack design as the GPG "Full Rut" which I've been hunting with for several years now. I like it. Mine is tough as nails, and quiet(almost saddle cloth like exterior, cant tell ont he "evolution" pack. The zippers are heavy duty. I feel like XOP may have called it the shadow for a while maybe?
The only thing I dont like about it is the pack itself is pretty heavy for the size.
