Sub Zero Titanium Water Bottles are very tough but extremely light, making them ideal for the weight conscious adventurers. The inert nature of titanium means no flavours or smells will be retained by the bottles, allowing you to switch liquids carried without worrying about taints.
The BPA and BPS free HDPE plastic screw cap has a large handy finger loop for ease of carrying and attaching to the outside of your pack. A replaceable silicon o-ring securely seals liquids within the bottle to prevent leaks when travelling. The 44mm diameter opening and clockwise tightening screw design fits most makes of bottle stoppers, including Klean Kanteen.
The 400ml titanium bottle is best used as your main drinking bottle when outdoors as it is easy to hold and relatively light when full, topping it up from your main water supply in your pack when empty.
