Exclusive & Limited. GeoPress® Titanium “Black Edition” is unlike any purifier we’ve ever created. Our signature CP4 Grade 1 titanium bottle is coated with an uber-tough, specialized Black Titanium PVD high-performance coating or extra protection. Titanium PVD withstands abrasion, corrosion, drops, fire, and even reduces friction while pressing. The extremely durable, low friction finish provides protection against wear and makes the bottle easier to handle and clean. Laser-etched in gold and dressed to kill, it promises to deliver in tough conditions and mock danger at every turn.
