A couple of photos of my Cuben fibre bags. Mine are based on a pair of Ortlieb back rollers, and made in Cuben(49g/sm). Not so well made and it was a test run for other stuff I want to make. Not super light but still quite a bit less than standard Ortleibs at 850g( 30oz). Been on one big trip with them in the Alps and their insides stayed nice and dry through a day long deluge. ( I didn't though :( ).
