The 15 Best Flasks For Everyday Carry

Jul 2, 2021

Category: Gear

The 18th century was a period of rapid technological development, and as such gave way to a slew of then-ground-breaking inventions like the atmospheric steam engine and diving bell. While the majority of new patents from that era have failed to stand the test of time, there are a few 1700s creations that are still widely utilized today such as the mercury thermometer and the self-contained fire extinguisher, though one 18th century invention that remains nearly as popular today as it did upon its introduction over three centuries ago is the modern hip flask.

Now having the benefit of more than 300 years since these stealthy liquid containers first rose to popularity, flasks are now produced in an enormous array of types and styles, typically varying in materials, size, and volume. Unfortunately, the vast majority of flasks that comprise the market are of the budget-friendly variety, often found at truck stops and smoke shops. If you know where to look, however, there is a small handful of more premium offerings utilizing higher-end constructions and employing more style-conscious designs — and it’s this top-shelf selection that we’ll be exploring today in this handpicked guide to the best flasks.

What Factors To Consider When Buying A Flask

The purpose and function of every flask is more or less the same, however, these discreet vessels can and do vary in a myriad of ways. Below, we’ll touch on four of the most important elements to think about when shopping around for a new flask.

Flask Type: Though the lion’s share of flasks on the market are designed to be carried in a hip or coat pocket, there are in fact other, less-common varieties such as the boot flask, or collapsible vessels that can be discreetly tucked in any pocket or garment. It seldom hurts to go with the tried-and-true — which in this case would be the classic hip flask — but it’s still worth exploring the available possibilities before ultimately making your purchase.

Volume: Flasks come in a host of different sizes and dimensions — with 6oz and 8oz being the two most common by a pretty significant margin. Most drinkers will find that a 6oz vessel is sufficient for most uses, however for longer engagements like weddings or camping trips, a larger-sized flask will often come in handy. It’s also important not to confuse a flask’s weight with its internal liquid volume when reviewing specs.

Construction: Gone are the days where the vast majority of flasks were crafted from stainless steel and today’s market boasts items made from an enormous array of constructions. In addition to primary constructions — which can be composed of everything from steel and titanium to plastics to polymers — many flasks employ supplementary constructions in an effort to fortify or accessorize a flask through the use of leather or silicone. Quite a few companies also produce flasks with special finishes or coatings over the main construction.

Style: Considering that the modern hip flask has existed for several hundred years now, it’s frankly unsurprising that more than a few individuals and outfits have taken it upon themselves to produce idiosyncratic or stylized interpretations of the traditional liquor container, whether that be through employing unique shapes or treating to flasks to vibrant paints of patinaed finishes. Before buying a flask, it’s well worth exploring a decent selection of offerings, as there’s a decent chance one of these more fashion-forward flasks might catch your eye.

Flask2Go Foldable Flask

Almost certainly the most stealthy and discreet flask available to date, the aptly-named Flask2Go is a collapsible and foldable flask that’s made from BPA-free plastic and is entirely devoid of any metal parts.
