Vargo Titanium Para-Bottle

Made of lightweight titanium, this 1-liter bottle from Vargo is completely biocompatible, meaning it won’t leach or corrode, & it works with common water filters. The screw-on lid is tethered to the bottle with a loop made of braided paracord—when you need some cordage in a pinch, it unravels to 7-feet in length.
