I just ordered a pair of patagonia french roast pants for $81 (30% discount) from www.rockcreek.com.
www.backcountryoutlet.com is also selling them for the same price.
These are the pants Ryan Jordan wore for the Arctic 1000 trip (see www.ryanjordan.com). He also has them on his gear list for his upcoming Absaroka Backbone trek.
They are stretch woven softshell pants that weigh in around 10 oz.
warning: the selection at both websites is limited to small waist sizes.
