So what about those stereotype shots of Mexicans sitting with their back against a wall and a sombrero covering their face while they take a siesta from the afternoon sun?

I've had no issues napping while sitting and using a bike cover as protection from the rain. You can literally sit IN it with your knees pulled up and the top pulled over your head for complete protection. The wool poncho I bring, folded, was more than enough cuishioning for the butt.

Most of the sleeping products on the market deliberately trade off simplicity for added comfort and convenience. Particularly important as people get older.

The thing is - once you get into tents - thats not just a sleeping system. A tent is a sheltered space that provides protection from insects as well as weather, room to cook, read, plan, and sort out, repair and manage a lot of other personal equipment. Traveling with one or more other cyclists - I wouldn't be without one.
