I ride my bicycle everywhere. School is a 5-mile commute. Jeans aren't the most comfortable thing to ride in, especially in the summer, but my 501s have the perfect rise in the back. I had some slim fit Lands End Canvas khakis, but a) the rise was too low and b) they were too small in the thighs for a cyclist. I also had some Ralph Lauren replicas of WWII-era military khakis. They were nice to ride in, although they were too full to be stylish. Other khakis I've looked at online have a smaller rise than 501s (I can't find the measurement for 501s right now). Are there khakis with a similar fit?
