Perhaps the most convenient water bottle out on the market is the Exotac Titanium Water Bottle.
The Exotac Titanium Water Bottle is made from 100% Grade 2 titanium that has been welded from three separate pieces. It looks heavy, but according to The Gadgeteer, it’s actually quite light. The icing on the cake for this item is the fact that you can actually heat it over a stove, so if you’re out camping, you can have boiling water without the kettle. The D-ring on top would be perfect for clamping it on a backpack as well.
Make no mistake, the Exotac Titanium Water Bottle is one that you want if you’re looking for convenience and style packed into one product.
