Update:

Poncho Liners are sold out!

Waterproof bags: I have had a lot of problems with them having pinholes in them, and I refuse to sell a not-so waterproof bag, so they are considered sold out.

I do have a different waterproof bag that is made out of nylon tarp (Just like the blue utility tarps to cover equipment) They are the same size (If not a big bigger) and are grey and green in colors. Same price if those interest you!
