Trousers made of microfibre or similar. The sort made as travel pants by Columbia. I wear them with the cuffs tucked into socks or around the ankle and held in place by reflective bands. They are pretty well windproof and presentable as streetwear just about anywhere.

Many of these sorts of pants come with zip-off legs to convert them to shorts. But I find the zip band to be a nuisance when they are converted to shorts and to be frank, out of the four pairs I own, I have used them as shorts about... twice.

I've now invested in a pair of proper long-leg pants, and use proper shorts. It might seem like it's doubling up in the pannier, but it's not really because in touring mode, I am usually wearing one or the other.

On our next tour, I'll be dispensing with the traditional cycling jerseys and going with technical t-shirts. I picked up several from MEC the last time I was in Canada. One was in Capilene, and all have a nice smooth feel, and are very light in weight.

I've also toured before in polo shirts, of the polyester variety, not cotton.
