Torso Max Heated Vest Liner - Made in the USA! Let's address the two main differences between the Torso Max and our normal Torso Vest Liner. First and foremost we are proud to say that this garment is made right here in the USA. Yup, you heard right...Made In The USA! The other main difference that you should care about is that the Torso Max will come with the extended life VB750RC rechargeable battery. This means you will have over 4+ hours on the highest setting and you can control the heat with the wireless remote. Other than these two key features, the Torso Max is roughly the same as our traditional best selling Torso Vest Liner.  This has been named the torso due to its slim fit and lightweight feel.  The way we keep it thin is by eliminating all insulation and combining a thin rip stop nylon layer with our patented Zero Layer® Heat System.  With its extremely low profile design, it will feel like a part of your body when layered under an insulated outer shell.  Using our four panel 7v™ Zero Layer Heat System, you will get hours of deep penetrating heat, allowing you to stay comfortable in the worst of conditions.  Rechargeable battery heated vests can sometimes be a little too bulky to layer comfortably.  With the Torso’s slim design you can use it for almost any activity.  This battery heated vest can slide under almost any garment which makes its uses almost unlimited.  The Torso is a simple garment that functions like a piece of equipment, allowing you to get the job done. The Volt heated vest liner will come complete with a rechargeable battery and a wall charger. The charger is compatible with 110V or 220V outlets and has a standard U.S. plug.  All Volt products come with a 30 money back guarantee if the products are still in new/unused condition with all of the original packaging.  Our goal with this guarantee is to allow you to check the fit once you receive your Volt Heat product.  FEATURES: Four panel heating system(one panel in the lower back and one in the upper back, two panels on each side of the chest) Includes one VB750RC 5000mAh battery, charger and wireless remote Built-in 3 level microprocessor controller to select desired heat output Provides over 150 degrees of soothing heat on high for over 4 hours and up to 10 hours on low Patented Zero Layer® heat system eliminates bulk while providing more efficient heat transfer.
