We are excited to finally be able to offer actual rubber ponchos and ground cloths! The ponchos are made with actual rubber sheeting, and have a cotton backing. They have the correct size brass grommets and the properly constructed neck slit. Our ponchos measure approximately 71x44 inches, which is close to the QM specs for rubber ponchos. Originals varied in length and width, but were all fairly close in variation to the QM specs. Our rubber is not sticking and is flexible and pliable. A great addition to any kit and long awaited here at SUM! We currently have several in stock and will continually restock. If you happen to order at a time we are waiting for a restock, there may be a wait of 3-4 weeks.
