North Texas does not experience really cold weather often or for a very long duration, but when it does hit we still like to ride. Staying warm and comfortable while riding in colder weather is important. I have found a great pair of jeans for those colder days or riding (or any outdoor activity for that matter). Cabela's fleece-lined denim jeans.
I wore the jeans on a recent toy run and I remained comfortable, even at highway speeds.
My video review gives more details. Check it out and then get you some!
