If you want a pocket on your chaps, it's an easy hand stitch job. I stole the side tool pocket off a pair of worn out Carhart's, and sewed it to the belt just aft of my hip. It worked fine most of the time...only once that I can recall I lost the scrench out of it. Fabbing up a flap top with a velcro closure would not be hard, if one wanted more security.
