When enjoying the outdoors in a cold weather environment you quickly feel the cold if you are not properly prepared. One of the first things to feel the effects from the cold are your arms and legs as your body preserves heat in your core to support vital organs. Brunton has produced the HeatSync Vital Vest to keep your core temperature warm allowing your body to circulate heat to your arms and legs.
Brunton is a world leader is outdoor adventure gear that is designed for professionals. Like all Brunton gear, the HeatSync Vital Vest is weather proof and made from a shock absorbing silicone exo-shell. This design allows you to be as extreme as your sport demands without being held back by a poorly designed or restrictive vest. The carbon fiber heating elements are extremely efficient while maintaining a low profile that radiates heat. With the power source being any USB 2.1A power pack, such as the Brunton B-Pack or Resync you are guaranteed easy and clean energy for your Vital Vest.
Nice fit and really adjustable for all sizes. Works GREAT! Has 3 heat settings. This thing uses a lot of power so I got 24000 mha battery pack, hoping to get 8 or 10 hrs of heat from it. I used it for 6hrs on lowest setting the first day and it still reads 95%, much better than I thought. It is a kind of expensive way to stay warm on a long motorcycle ride, but it works and I glad I did.
