This adapter is pretty much awesome, it of course mates perfectly with my Dromlite bladder… it also mates perfectly with my nalgene bottles… total bonus! I use my MSR HyperFlow Filter to pump water directly into my Dromlite and nalgenes… it's just a push and a twist, and the pump and adapter are connected. Smart MSR design – Easy to use.
