While we all realize the fever of cuben fiber known as dynnema, the super ultralight fabric comes at big expense and if you are trying to stay in a moderate budget is nearly impossible to acquire.
By doing some basic math for a DIY project, the expense is nearly the same, and requires proper skills, time and a good set up.
We recommend Membrane 0.93.
The MEMBRANE sil line was developed with one goal in mind – create the lightest, most waterproof fabrics on the market.
Same silpoly benefits of lower water absorption (i.e. no sagging) and increased UV resistance, but in a waterproof textile that’s 15-30% lighter than traditional lightweight coated nylon/polyester fabrics.
MEMBRANE Silpoly is the ultralight version of our MEMBRANE silpoly line of ultralight coated materials. At a finished weight of just 0.93 oz/yd2, it is the lightest waterproof polyester textile available. The material features the following:
- Custom woven, high-thread count 15D polyester
- Plain-weave construction
- High-quality sil/PU coating on each side
MEMBRANE Silpoly is best for situations where you want the lightest possible waterproof fabric outside of Cuben Fiber. Lower water resistance than the PU4000 version, but ~15% lighter.
A premium material for all projects requiring an extremely lightweight, waterproof textile. Common applications include tarps, tents, ponchos, gear sacks, pack covers, etc.
*Note: this fabric is the exact same on each side. If seam sealing, we recommend using a 100% Silicone sealant such as Sil-Net.
A few examples of this product can be found at UGQ (underground quilts) among other manufacturers. Their bivy tarp solo weights 6oz with a comparable space coverage of a 5 x 9 CF tarp for only $110.
