If you can get your way to sportsbikeshop then try and order some bull-it to try on, cheapish for motorbike jeans and the fit my short stubby legs quite well. I have covec tactical slim and stealth 17. The covec are tougher and I wear them on the commute and most of the day at work unless I have meetings. The stealth are much lighter but probably closer to what your brief is. They come with a stealth armour which i find a bit flimsy out of he box so have stuck some stiffer material to the back of to make it less flexible.
