I have the Triumph highway jacket that they unfortunately don't make anymore (it is such a cool jacket). It has a liner and I've worn it to as low as 27 degrees. Of course I had a sweatshirt and a thermal top on underneath that and was thankful for the stop lights when I was riding home that night (for a chance to feel the heat coming off the engine). It took a while to break in but the Triple collection leather gear that I've seen seems to be very good (a little pricey but very good).
