I always wear my Diamond Gusset kevlar lined jeans when riding. Very happy with them...lots of neat features and they are made in Georgia for the TN based company.
I got the Sliders. Damn good riding jeans and comfortable. I also wear full protection gear most of the time. Sliders when I'm lazy.
Don't let others mess with ya about what you wear for protection, it's what you don't wear that you need to be lashed about.
