ULTRA TNT Tarp: A Dyneema Alternative?

While looking for a tarp more waterproof than Sil-Nylon AND something cheaper than dyneema I came across Ultra TNT Fabric. Then discovered that Etowah Gear makes tarps out of this material. Though cheaper than dyneema it is still fairly expensive. I got us a 10x8 tarp anyways to give it a try. Join us as we check it out for the first time!
