Hydrapak First Wave Military Reversible Hydration Bladder Reservoir
Hydrapak First Wave Military Reversible Hydration Bladder Reservoirs are designed keeping the heightened abuse that may arise in extreme situations in mind.  The 4mm thick thermopolyurethane (TPU) is twice the thickness of our consumer model and comes with a reinforced slider top to match.  Additionally, the First Wave utilizes our proprietary one piece Hydrofusion Insulated Big Bore tube that is lighter than standard neoprene insulation and has the insulation applied to the tube rather than covered with a sleeve. All of these advanced features combine to make a hydration reservoir bladder that you can really depend on!
