i want to get some riding pants, but i don't really know what makes a good pair of pants. are the ones that look like jeans just thick jeans? seems kinda dumb. and are the textile ones any good? it seems like they are nylon and that doesn't sounds like much protection. so does that leave leather as the only selection? i would like something that i can wear when i get off the bike too. i have a Teknic Lightnight jacket now, so are there pants that zip on to that jacket? any info would be great, thanks.
