Cold air presents a serious threat to the body’s vital organs and systems. Helping prevent rapid loss of body heat, the new Hot Rox balaclava captures heat from each exhaled breath and brings it back to our body’s core—easing breathing and allowing workers to maintain full lung capacity in the most extreme winter conditions. The N-Ferno 6970 Extreme Balaclava with Hot Rox will be available December 2011. www.ergodyne.com
