I drank the Rivendell kool-aid and it was damn tasty. I bought 3 pairs of MUSA shorts on discount before they were discontinued. It was a mistake not to buy 3 more.
For the future I plan to try out these touring shorts, they look nicely made.
Bike Shorts from People Who Really Know Bike Shorts!
As for shirts, sometimes modern jersey, sometimes wool, sometimes cotton t-shirt. Depends on how hard I'm riding.
