I wear a pair of Hood K7 Black Jeans, having not fallen off whilst wearing them (touch wood) I can't comment on how effective they are when sliding down the road. I also purchased the knee and hip protector inserts, which I find are really simple to fit into place and once there, they don't move around or require readjusting (I like simple things ) They're comfortable and feel just like a normal pair of jeans, they don't look too bad either, no they're not going to compete with your £150 pair of Diesel jeans for looks and design, but that's not their purpose. In terms of protection, I feel safe in them and comfortable with the protection they should provide, obviously they can't compete with a pair of leathers, but for what they are, I'm more than happy with them. I took a couple of pictures for you (front and back), to show you the para-aramid lining, as you can see it doesn't cover the whole of legs, with the lower parts remaining exposed but much of this is covered by my boots, so I'm not fussed about it. Hope this helps in someway.
