Ultra-Lightweight ground sheet made from "Tyvek"-type material.
Big Sky International says:
ShelterSaverTM is made from lightweight, yet durable non-woven fabric. Corners have S-hooks that are used to attach ShelterSaverTM footprint to tent.
Big Sky International's Revolution/Chinook 2P Footprint are made from similar stuff to Tyvek which is a material taking from the house building industry and has been adopted by the ultralight community for many different purposes. It's very lightweight and waterproof. Big Sky have made it their standard material for all of their groundsheets. They've also managed to get it really soft and malleable whereas sometimes you can get Tyvek that's stiff and crinkly that develops weak points at the folds so that's a real bonus.
