We listened ! The water bottle holder which we offered on our All Day Pack is now available on it's own. The stout hypalon fabric provides rigidity and support for full size nalgene style plastic bottles, while the strap system allows it to scale down to hold any size water bottle, or two cans stacked on top of each other. Works on any pack with an strap from 1" to 2" width, really works wonderfully on our net holster. Great way to stay hydrated on the water.
