I've had one of those Misty mates for about 10yrs now,& It's still working,they hold about 2Pts of water,you pump it up,clip on the hose to your collar/hat/or just point it wherever you desire,at friends,etc.,It put's out a steady cool fog,especially with an Icecube or 2 inside,well worth the $12 I paid so long ago!Tarpet,wallyworld still sell them!YMMV-Especially if you reside East of the Rockies & North of Parkfield!
