Query: Too small

I bought this to hold back my pant leg to keep it from getting caught in my gears as I ride my bike, but it is very small. It is probably OK if it is just going around your ankle when you are wearing thin socks, but it is not long enough to go around pants. I had it fall off soon after I began using it. Though I found it in the road a day later, I can't trust it to do what I need for it to do. I have replaced it with an adjustable strap that clips on (instead of just relying on velcro to keep it closed) and which emits a light instead of just reflecting it.
