Nice assortment of tinders! Lately I've been carrying a "fire bag" when out in the woods. It's about the size of a soda can and made of sil-nylon. It didn't come seam-sealed so I DIY sealed it with silicon; I can fill it with water and it doesn't drip thru the seams now. It has a drawstring closure so wouldn't want to immerse it but it's highly water resistant. I keep various fire making items in it. Of course, your tinder pack is much more compact and easier to carry!
See, now I want something bigger... :-) KIDDING! sort of.
My son has also put together a little bundle of kindling that's got some fat wood and an assortment of branches. I'm on the hunt for some sort of bag for it and you sil-nylon bag sounds like a great solution. Thanks Phaedrus!
