Nonbulky warming vests offered

摘要

Without the added bulk of natural or synthetic fiber, this new N-Ferno 6900 Warming Vest with NobleTek Insulation is available. The Argon-insulated vest offers exceptional warmth, comfort, and flexibility. Instead of trapping dead air in thick cells, the vest uses flexible, airtight, yet breathable chambers filled with Argon gas. N-Ferno's 4.5-mm Argon layer has the same thermal conductivity as 14-mm of the best synthetic or natural fibers currently available, declares the manufacturer.
