1680 denier Ballistic™ material
“Ballistic nylon is a thick, tough, synthetic nylon fabric used for a variety of applications. Ballistic nylon was originally developed by the DuPont corporation as a material for flak jackets to be worn by World War II airmen. The term ballistic nylon takes its name from the fact that it was intended to protect its wearers from flying debris and fragmentation caused by bullet or artillery shell impacts…” – Wikipedia
Now, this begs the question, that if the brainiacs at Dupont felt that this material was good enough to protest pilots from bullets and shells, don’t you think it would be the best material out there to protect your gear?
It you want to get technical, it’s a 2×3 basket weave, which is one of the strongest types of weaves. 1680 is the denier, which is an indication of the weight. As a comparison, most other bags on the market are made from 840 denier (because its cheaper and easier to sew) some are even lighter. 1680 denier nylon is used on ultra high end luggage like Tumi™or Briggs and Riley™. Its not cheap, but then again, the Portare’ bag isn’t either (just the price is!)
