Credit card and passport Dyneema Fiber Composite drybags

[edvin mellergård]

I was going through my stash of fabrics yesterday looking for something and found a piece of 34 gr/m2 (1 oz./yrd.) cuben  Dyneema Composite Fabric I bought maybe 8 years ago(?) and used for some other projects.

Now, last weekend when I was out on a bikepacking trip I carried my full wallet and keys -> Loads of unneccesary weight. So I decided to do something about it.

I used some of the cuben fabric to make four of these tiny drybags for me and my girlfriend. Two that fits a couple of credit cards and a house key inbetween the credit cards and two larger one’s for when I travel abroad and need to bring my passport.

My scales hover between 3-4 grams for the smaller one and 6 for the larger one. I’m a bit afraid that the hard edges will wear through the Cuben but we’ll see :)

My driver license, cash, and credit cards are waterproof. My passport is water resistant, so stamped impressions might run if they get wet. I have a small Cuben sack with a drawstring to help prevent losing them. A zipLock would serve the purpose just as well. My only concern is loss, not water damage.

Anyway, those little bags you made are nice looking.

Nice little bags!

I’ve been using a ZPacks zip wallet in hybrid cuben for more than a year now as my daily wallet. It’s a great material and the zipper is supposed to be waterproof other than the little gap at the end where the slider lives. Good stuff.
