I have been toying with the idea of making an inflatable pillow and possibly a sleeping pad. This is the very first creation. As you can see where I inflated the pillow it has been sealed. I didn't use a valve since this was just a test. I wanted to see how durable the material was and how the seams hold up. A 72x20x2.5" pad made of this would weigh 11oz with the valve.
Here are some numbers.
Weight: 15.3g
Size: 12×6
Material: special coated ripstop nylon
For testing I have been sitting on the pillow for quite some time with no signs of trouble. I tried the bic pen test with some scraps and it is reasonably durable for its weight. Of course I was able to puncture it but it took a decent amount of force.
