This adjustable bottle holder fits thin beverage containers like the awesome 20 oz. Zojiroushi insulated stainless steel travel mug or fat bottles such as the giant 32 oz. Nalgene Tritan wide mouth bottle (pictured above). This rig will even adjust to fit a growler.
The holder is constructed from full grain Saddleback Leather Co. scraps and up-cycled Army surplus leather bedroll straps. Some copper rivets & burrs, recycled d-rings, Stormtrooper medallion, Microsoft carabiner and hand-sewn thin polyester waxed thread complete the build. This is the last item I made with the thin thread. I’ve since moved to thicker heavy-duty polyester.
