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.

*

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: Freeze many bottled waters, keep them in a cooler.  Swap them out when the water get warm.

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.
