We are constantly making our products better. To thank you for your loyalty, if you have any older versions of OUR Heated Liners, you can get a discount by agreeing to send the old one in for the newest design. If you have one made by some other company, you can trade that in also but not for as much of a discount. But still it is a way to get rid of less quality product.
All Our Heated Gear should be used with an optional Heat-troller™
