I had been looking for some decent non-spandex knickers some time ago and, well, the page that I found on the internet is gone, but here it is elsewhere:

I haven't bought them, so I can't give you a review. Don't know if the pocket fits your lock or if the price fits your wallet, but I think it'll pad your bum.

Let us know what you find and if you recommend!

Zoic is among the brands that innovated the bike knicker, and baggy shorts, as a replacement for lycra. One of Zoic's founders now owns Xoom Juice here in Tucson.

Prana has their Mantis Knicker.

The women's version of this is the Moto Capri.

Bike Fixation sells an excellent Classic Wool Knickers and Hemp City Knickers.

I lust for Chrome's Lightweight Shins as well as their Pacer top. Alas I don't have the dollar for those lovely items.

My suggestions don't include a padded bum. I use liners for that and wear the knickers over. The Zoic shorts have the padding as an integral part.
