Cuben Fiber rain pants

I think rain pants are the least-used item in my pack. I still remember my first rain pants; a pair of rubber overalls that probably weighed in at a few pounds. I've had many pairs of rain pants since then. The last pair I purchased was a pair of o2 rainpants, weighing in at 126 grams (4.4 oz). That's pretty damn light, but I still don't feel good about carrying around an extra 1/4 pound of rain pants that I've only ever worn twice. So I recently ordered some cuben fiber and got to work.

The cuben fiber I'm working with is CT0.6K.08 and weighs 15g/sq. meter (0.5 oz). I initially bought it with the purpose of making stuff sacks, and had the idea for rain pants along the way. I dissected a pair of old EMS goretex rain pants that had long seen their glory days. I then laid the parts out on thick plastic and made a mock pair to try on. They fit well, so I was able to use the mock-up parts as a pattern.

I'm using cuben tape for all the seams, and some leftover elastic cord from my tent poles for the waist. The finished rain paints weigh in at a whopping 35.5 grams (1.25 oz)! I think I've achieved absolute minimum wieght on these. Here are some pictures:

and they pack up small too...
