They are by German company Bahidora. They weigh 407g on my scales but the official weight is 430g. Size is 188cm x 55cm by 5.5cm thick. Material is 20D ripstop nylon. R value is 1.3. They don't come with a pump as they are intended to be inflated by mouth, but an exped pump sort of fits if you wrap a rubber band around the nozzle.
