Tyler/Ken - I will not be putting these on my website for right now, I'm not ready for full time production, but I will do them as a custom order. They are $250 shipped.
Ike - I fill all my products using the mesh-over-tube Shop-Vac method. PM me if you need further details.
Konrad - I can source any materials that are available to consumers to make my products out of. I don't necessarily stock everything, though.
Jim - Cuben Fiber is an interesting fabric. It is stiffer than nylon or silnylon, but is not really crinkly. On a noise scale from 1 to 10, I would rate nylon as a 2, silnylon as a 3.5, cuben fiber as a 5, spinnaker as an 8, and the recyclable Sun Chips bags as a 10.
