The Kumfie Sit Mat is one of those little widgets you didn't you know you needed; but once it's part of your packing list, it's pretty soon essential. Instantly solves the perennial problem of the grass-dampened derriere. 

Made from polyolefin cfc-free foam, it's super-lightweight and is about the size of an A3 sheet, big but small enough to fit a daypack.
