FAQ

• Some reviews say the Bladders leak, why?

        Most bladder damages are caused by the zip.  Do not let the edge of the water bladder get in the zip and force through.

       The detachable Bladder!  The whole bladder can be frozen. The cooling time will be 80% - 100% more than the 2017 version.  The high quality fittings will cost $20.00 more.  

• What's the Different between this vest and $219 one?

 

        The $219 one is "All-In-One" and 2 litre bladder; this one is separate backpack and 3 litre bladder

• How long will the ice last?         

        The actual duration depends on a) how much "cold" you start with; b) how rapidly heat is absorbed.

        *Tips: add alcohol to water, lay flat in freezer, move the air bubble to the connectors, freeze the bladder overnight. Buy a few more bladders.  

• How long will the battery last?

• How to tell if the water is circulating?

        There are an inlet and an outlet on the back of the Bladder. The higher one is the water inlet; and the lower one is the water outlet.  Fill water to the minimum water level. Turn the pump on.  If you see the water is coming back from the inlet, that means the water is circulating through the vest.
