I've finally taken the plunge and ordered some cuben fiber. I've been curious about it for a while, and decided to get some for making stuff sacks out of. Well, here's my first stuff sack. It's for my tent, and weighs 8.9 grams (0.31 oz). The cuben fiber I'm working with is CT0.6K.08 and weighs 15g/sq. meter (0.5 oz). It's put together with cuben tape. There will be more cuben fiber projects for me in the future!
