Snow Peak’s large rectangular pocket-friendly hip flasks don’t hold much, and they don’t fill or empty fast. But they can provide you with precious emergency supplies of good drinking water for those moments of need – just enough to tide you over until you reach more substantial sources.
Try to find (or make) a pocket for this flask to fit snugly into. For example, the small mesh compartment within the large zippered pocket on either side of Helikon-Tex Pilgrim Pants holds this flask so perfectly that you might forget it’s there. This can be a good thing, because consuming your emergency supply when you don’t really need to, just for convenience, may be unwise.
Biocompatibility
Titanium is fairly inert, compared to steel or aluminium for example. Drink connoisseurs observe it doesn’t noticeably taint the taste of one’s beverage like these other metals do.
But it’s not perfect: Dentists observe around 5% of titanium implant customers complain about adverse reactions – for this reason, ceramic (zirconia) implants are often offered as a more biocompatible alternative.
Titanium is not edible enough to consume in leaf or colloidal form, but it weighs and costs a lot less than solid gold or silver. It’s also less inert than glass, ceramic and gemstones tend to be, but it’s far less fragile than these materials.
So if you’re picky about your water vessels, perhaps consider carrying a glass bottle or jar in a padded carrier for your main water supply, while also carrying a titanium hip flask or bottle as a more durable emergency drink container.
