Last year, I read some positive feedback on these forums about the Club Ride Woodchuck liners which were described as "3 hour liners." I was a bit skeptical when I received them because they seemed a bit skimpy but they did in fact perform well as 3 hour liners. Can you recommend any other 3 hour liners made to this level of quality? Also, what liners do people wear when they want to bike for 6-8 hours?
