Tour Master Synergy 2.0 Heated Chap Liner 4.8 5 10 10
Great feeling without the bulk of full pants Great extra layer to add heat to the lower torso, being a big guy wearing insulated pants, heated pants and over pants becomes a lot of bulk, by wearing the chaps design it dose not feel so bulky but offers great warmth and added protection from the wind & cold, so easy to put on and take off and works great with Tour Masters heated jacket for long rides in New England during the winter months!!! :) November 4, 2015
So fast to put on, and light weight, yet so warm! These liners are extremely light weight, yet very warm, and fit perfectly under our chaps. They make a huge difference over just chaps. Plus, for us guys, almost no zipper interference for those all important rest area breaks. Many riders may question the use of chaps period, let alone a chap liner, so allow me to give you my reasoning. Chaps protect what needs protecting from cold wind, without adding bulk, plus they are extremely quick and easy to put on and take off. While many pants have side zippers, I wear a size 14 shoe, and trust me when I say that its still a struggle to get overpants on, and many rain pants simply will not go on without taking the shoes off first. With these, I can be ready to ride in cool to very cold weather in minutes, and still comfortably walk around a mall or eat in a restaurant without feeling overheated or unable to move. To me, these are perfect, even if you want to wear them under full pants, which I have done as well. April 6, 2015
Passenger comfort Bought these for my wife after much research by her. She has worn them over jeans by themselves and also under wind pants. She was more interested in keeping the knees and thighs warm. Heated seats on the bike keep that part toasty. Ordered a wireless two channel powerlet controller so she could pair them with her Gerbing jacket. Allows fine tuning of her comfort. Only got two weekend rides in before it got too cold for her, but both uses got a thumbs up. December 30, 2014
Chaps provide plenty adjustability and warmth I've only had the opportunity to wear these 3 times since receiving them, but I'm very happy with my choice. I ride a R1200RT, and wear these along with a Powerlet heated jacket liner plugged into a wireless dual controller under my Roadcrafter Light gear. So far, the coldest ride to work was in the mid 30s and I was nice and cozy. The chaps fit true to size. I wear 34" waist/32" inseam trousers, so I ordered the Large size to get the inseam lenght. There is plenty of adjustment in the waist and legs to go from "chicken legs" to "ham hocks". The heat is evenly spread with no hot spots noted. November 24, 2014
Great addition for colder weather riding I try and ride as much as I can on a 110 round trip commute to work, even in colder weather as long as its not below freezing. I already have an electric jacket liner and have used a couple of years. I bought these chap liners after looking at pant liners and heated over-pants to extend my comfort level when riding at 0300 hrs in the morning. I went by the size chart and ordered the appropriate suggested size. Had to send them back and get a different pair as they were way too big. The new ones came and fit great. I've used them a couple of times under my leather over-pants and textile riding pants with great results. They plug directly into my jacket and are easily regulated by my single controller. Great value for the $$ spent and stop the wind and give you added warmth. Not the most stylish item in the store but they are liners and work as advertised. My only negative comment is that I wish they had made the connector plug/lead from the pants a little longer. Its only a couple of inches long and shortens the reach of the connecting pig tail.

enjoy ease of putting on and off easily So far the chaps are comfortable and warm enough, can wear them under our leather chaps in rainy weather. July 7, 2014
Great product, fits under regular chaps and is WARM! We now have heated chaps, glove liners and jacket, they all work great and make riding comfortable when the weather changes. They pack up small and can be stored in a saddle bag when not used. All you need to wear is a t-shirt and regular clothes and this keeps you warm. No need to bundle up and have to take off layers when you arrive somewhere December 23, 2013
