Back to clothes, I follow the pattern suggested here I think by Oregon Mouse (good luck with Hysson)some time ago. The clothes I have with me can all be worn at the same time (including into the sleeping bag), and, in total will keep me toasty warm on the coldest night I am likely to face on a given trip. If I'm wearing boots for a particular trail, I will also carry crocks, and I have spare undershorts and socks, but that's about the extent of my duplication.

I also have a poncho and rain gear, but the poncho is also my shelter, and my rain gear is what I wear in town while everything else is in the laundry. The jacket doubles as my wind shirt, and I use the rain pants when the trail conditions require long pants.

Aside from what I've mentioned, I'm usually wearing shorts and a short-sleeve shirt (often over wicking T-shirt). I typically carry a WM down vest, a set of lightweight silk longies, a fleece cap and light fleece gloves. That's it.

Hope this is useful. Best, jcp
