+1 on the Andiamo. I also have some from REI and they appear to be clones of the Andiamos. I have been using these to commute in for about 4 years and I can wear them under my regular pants after I get to work. I ride in REI Headwinds pants in the colder seasons and then zip off leg hiking pants in the summer. Can't say enough good things about them a lot lighter than regular bike shorts so they are cooler.
