wicchunter, give Jeff a call at
www.graywolfwoolens.com and ask him about Wolfskin if you're looking for the absolute best material you can buy in Predator... Turkeystalker mentioned Enigma; it too comes in Wolfskin, and if the company has refined its pattern, it may well be worth looking at too. I think you'll find them at
www.enigmacamo.com.
Wolfskin is not waterproof, but I guarantee you it's about as water repellant as you'll find. It would take a serious, serious downpour over an extended period to soak through Wolfskin. It's also extremely quiet and pliable, and is not made up of separate layers with an adhesive between them, which causes other materials with similar properties to get stiff when frozen.
