Clipped from UKASC, this is something that should interest us Canucks: Arte Corporation's MOLLE GBB mag heater:
"Some more news courtesy of Corporal, and another novel idea, a battery powered Semi-conductive Heater Built-in, Hot MagazinePouch. It is the size of a normal GBB MOLLE magazine pouch and keeps the mags at a toasty 25c and available in OD. Japanese RRP is 5985 YEN or roughly £28 which is about the cost of a normal GBB mag pouch. Should be ideal for next winter or if the current weather is anything to go by, this spring."
