If you’re a fan of running, but hate feeling hot and sweaty, there’s a gadget just for you – as long as you don’t mind looking like an escaped prisoner from some sci-fi movie. Called the CoolWare Personal Cooling System, this battery-powered device attaches to your neck and does everything to keep you cool. The CoolWare Personal Cooling System is touted to refresh your entire body through the use of a 2-speed fan and cool water that chills the anodized aluminum band wrapped around your neck. Requiring a refill every 2-4 hours (depending on your usage), this device is the perfect companion for those hot summer days. The CoolWare Personal Cooling System is available now for $49.99.
