I just ordered the tourmaster synergy electric jacket liner. I am tired of freezing! I looked at the gerbing but went with the tourmaster after much deliberation. I got the jacket liner for $156.99 shipped to my door which includes the battery connector and thermostat. Gerbing sells the jacket liner for $199.00 plus you have to purchase the thermostat seperately for about $69. Harley-Davidson sells the exact same product with their name on it for $220.00 plus the thermostat. The tourmaster comes with a 3 year warranty vs. gerbings lifetime. I will do a product review after I have used it a few times in the cold and rain for those interested in the product. I live in the southeast but am planning on riding to Alaska late in the summer so I think the electric heat will be welcome north of Montana in August.
