What have we learned since the creation of our O.P.P. (Optics Protection Program) more than 10 years ago? A hell of a lot. And we crammed all that experience and hard-won knowledge into the D Mag. This handy, 285-cubic-inch carrying case has an ergonomic design that sits tight to your chest for mobility, and wide, vented shoulder straps that make all-day carry effortless. The Zip-No seals on the bino and rangefinder compartments keep gear safe, and open silently. You invested in great optics. The D Mag is the insurance they deserve.
