For long rides I'll wear the right gear but around town I tend to just wear jeans - thinking this is something I should change. Problem is though to me Draggins and the like seem overpriced, especially since without armour they aren't going to prevent a shattered kneecap anyway. Now I know you can get armour for Draggins but I've been thinking it would be easier (and cheaper) to just strap dirtbike knee protectors over the top of normal jeans. They're certainly cheap (30-50 bucks for a pair) but not sure how well they'd protect against impact or abrasion (though really only talking 60-80kph maximum). Is this a feasible option or am I just crazy (or both )?
