When only layering up will do, or you need the added flexibility of leaving your arms free, the Thermite Fleece Vest has you covered. Remarkable warmth is driven by four patented Microwire™ heating zones encapsulated by a lofted anti-pill composition. This vest keeps you warm as you tackle the elements face on. Available in Black, Navy and REALTREE XTRA. Powered by our Gyde 7v lithium ion rechargeable battery (sold separately).
