After seeing a couple of threads here about how riding jeans are not theat good, and I usually ride in Duluth fire hose pants, I was looking into getting a pair of riging pants for the summer. I came across the First Gear Kilimanjaro pants. They state they are made of 420 denier nylon. Is that any good? Would I be better off just wearing my fire hose pants. I cant afford to spend a lot of money. Trying to put my daughter through school, but I want to be safe. Considering a jacket also.
