This fits your .
In a brief moment of design enlightenment we created the very Versatile Wolf Bottle Holster. We worked the design around the popular Optimus, Primus, and MSR 1 liter bottles. The Bottle Holster can attach to the seat, rack ,or to Expedition Dry Saddlebags, Rocky Mountain Saddlebags, E-12, Day Tripper, Enduro Dry Saddlebags, and just about any where you can strap it to. . Works perfectly with Rolie Bags and the Escape Pak. This is an easy and convenient method to carry 1 liter of extra liquids.
