I wear Draggin Jeans Drayko Drift. I get compliments on how good they look (like designer jeans), and they get much better slide protection than regular jeans. With the armor inserts, protection only gets better. I wear these because of one important factor: the best gear you will buy is the gear you actually wear.
I rarely wore my mesh or leather pants when I had them because they are SO uncomfortable (hot... hot... hot), and about 50% of my riding is because I am going out somewhere (I totally ditch my cage in the summer). So it was incredibly tedious to me to have 19 different items of gear I have to both remove and then find some place to store, or face the punishment of lugging them around with me all day. That said, I will still wear 19 pieces of protection if I am doing a very long or hard/twisty ride. But for city travel and nights out to the pub, my trusty Drayko Drift, gloves, boots, Joe Rocket mesh jacket, and helmet all do the trick.
My Joe Rocket jacket has clips on the back that can be attached through belt loops or an actual belt. I'm not sure they would survive a huge impact but it is better than nothing. Most important of all: it spends less time in my closet than my other gear. I love my kevlar jeans! They are very cool when they need to be and yet warm enough to keep my testicles intact on those nippy 4am rides to work! Highly recommended. So much so that I bought 2 more pairs.
