This FirstGear Heated Jacket Liner requires a heat troller (sold separately). You must purchase at minimum a single heat troller for this item. Gloves will attach to the liner with no additional troller required as long as you do not wish to set the gloves and jacket liner at different temperatures. Trollers can be mounted or not to the bike depending on troller purchased. A remote for heat control is also available. BMW riders will most likely have to purchase a converter for power. The power for these items comes directly from the bike which you must install. If preferred, you can purchase a portable battery pack with optional a/c adapter (case optional as well). Splitters may be purchased to connect an additional rider to the power source from the bike.

Jafrum has the best prices

by - verified purchaser
As you can tell, I bought the whole outfit, the cost made me take three days to finally hit submit. It was worth every dollar for the outfit. First gear is the way to GO!!!! And Jafrum at least gives you bucks for your purchase. And their prices are comparable to sites that give you nothing in return for the cost!!!!!!!!

Great Products

by - verified purchaser
It's worth getting everything, I got the First Gear Heat Gloves, First Gear Heated Pant Liner, First Gear Heated 90 Watt Jacket Liner, and a Dual Remote Control Heat Troller Kit. Pricy but very comfortable. So Far I drove in 37 degree weather and windy. Well worth the investment.

Keeps you warm

by - verified purchaser
So I just wore the pants , with the jacket liner and the carbon gloves for the first time ! All heated up in about 5 min ! It does keep you nice and warm , think of it like a heating pad around your chest , legs and hands . About 30min into the ride though I noticed that my heat was gone and the lights on the control was out . I stopped and had to take a look at the battery and found that the 15a fuse on the control had melted :-/ I will be riding tomorrow for a couple hours and hope this doesn't happen again ... It does have me concerned and that is why I say 4 stars ..

FirstGear Heated 90-Watt Jacket Liner Review

by - verified purchaser
The older I got, my tolerance for cold weather riding diminished considerably, cutting my riding time to 50 degree days and running for th' barn when the sun went down. Thanks, Jafrum, for setting me FREE again. My First Gear 90-Watt jacket liner keeps me WARM and TOASTY with plenty of heat to spare and was the best value of any other site, INCLUDING free shipping. Saving my 'chips' for the whole outfit that somehow, didn't make it into my XMAS stocking.

"For the comfort and safety during winter riding, it is worth paying for winter gear. I love firstgear's heated clothing. Bought the gloves too."
