Compcooler 3x/4× personal cooling system camelback. Condition is "Used". This was wore three times. Everything looks like new minor discoloration in bladder holding bag from water which is in photos. This is a 3x/4× I normally wear a 2x this fits me just a little big. I purchased it for a disney trip I hate the heat it worked and still works awesome it probably lowered by body temp by 20 degrees and lasts 2 to 3 hrs on one ice pack. Then all you do is reload a new ice pack and your on your way. We went biking deep sea fishing and lots of walking and it worked excellent for all activities. Why am i selling it? I live in Pennsylvannia and its winter and I just got laid off. This comes complete with charger bladder jacket and pump. It easily holds a charge for 8+ hours of operation. Comes qith original box.Thanks for shopping Darren
