The 9 Best Flasks of 2020

Boozy canteens for everyday carry.

Whether your choice of drink is a single malt or a bit of hard lemonade, a good flask will make discreet drinking much more pleasant. And while you may think any old flask will get the job done, there are a few things to consider.

First off, know where your flask will be carried to—is it for warming sips on big adventures, or for sly drinking? Second, pick your material accordingly. If your flask is going to be slipped into a suit jacket, consider a sleek leather case. If it will be tossing and tumbling in a backpack or hiking bag, consider a flask with a durable exterior. Either way, you’ll want a flask that won’t leave a metallic taste in your mouth and has an opening wide enough to sip comfortably. 

That said, see our picks below of the best flasks available that range in quality, character, and price.

Best Overall: Stanley Classic Flask

Stanley Classic Drinking Flask

Amazon

Stanley’s classic drinking flask is as quintessential a canteen as you can get. It hits the perfect sweet spot of affordable, thoughtfully constructed, and ultra-durable. The tote-anywhere flask has a sturdy, reliable body and holds a healthy 8 ounces of liquids.

Made of 18/8 BPA-free rugged stainless steel, double-wall vacuum insulation keeps outside temperatures from affecting your flask. Opt for the retro, 70s-inspired Hammertone green color, or give your flask a more updated exterior with Polar white or matte black options. The never-lose cap is built into the design—no hunting for a dropped minuscule cap on the forest floor.

Hip flasks are usually designed to be petite (they traditionally fit in a pocket, after all) but the Stanley flask is available in 5- and 8-ounce options. Or, upgrade the flask to a set that includes four handy shot glasses.

Best Splurge: Snow Peak Titanium Flask

Snowpeak Titanium Flask

Snowpeak

Though Snow Peak’s elongated flask is a splurge, its Grade A titanium construction reflects that—it will hold up for years to come. Each flask is made with care and finished by hand in Niigata, Japan, with methods that have been passed down for generations.

The titanium flask is a step above a stainless steel flask—the material is stronger than steel, and boasts highly inert properties that make the metal incredibly anticorrosive. Titanium also doesn’t hold the flavors of its contents, so notes of peaty scotch won’t linger far after you’ve sipped the last drop. Each flask holds six shots of liquor (or 5.8 ounces), though smaller 4.7-ounce versions are also available. All flasks come with a synthetic leather case, a custom gift box, and a replenishing funnel. 

Good to Know:

If you tend to misplace things, keep an eye out for flasks with attached lids. Or, opt for a brand, like Snow Peak, that sells replacement lids.

Best for Outdoors: GSI Outdoors Boulder Flask

GSI Outdoors Boulder Flask

Amazon

GSI Outdoor’s lightweight flask is prepared for all terrains: it’s wallet-friendly, super-tough, and carries a hefty 10 ounces of booze. The flask is made with durable, shatter-resistant copolyester resin, outfitted with a grippy silicone bumper—drop it, bump it, and the flask will prevail. (Though note that its construction makes it tough to slip in pockets.)

The boulder flask has the classic appeal of a glass flask but without the risks of breaking or shattering it (and the cumbersome nature of glass flasks). The clear exterior means you can tell exactly how much booze is left. The exterior of the flask is marked with graduations for simple measuring, while the opening pours easily and is large enough to sip from comfortably.

Best Value: Rabbit RBT Flask

RBT Flask

Williams-Sonoma 

This sleek flask from Rabbit is one of the smoothest ways to store liquor on the go. A subtle cap hides the traditional flask shape, but pop off the cap and you’ll find a smart flask model. Each flask is designed by a team of wine and cocktail lovers out of Seattle—the designers combine form and function, classic shapes, and pure geometry. Case in point, this updated hip flask is perfect for the modern drinker. A suave, matte black silicone exterior with classic gold accents gives a subtle art deco appeal. 

Design aside, the flask is made with high-quality stainless steel and features a leak-free lid that snaps open and closes with ease—no twisting required (in other words, you can open the flask with one hand). Each flask has a liquid capacity of 6.5 ounces.

Best for Sharing: High Camp Firelight Flask

High Camp Firelight Flask

Huckberry

Well-suited for taking on a quick hike, camping trip, or to the park, this share-ready flask from High Camp comes equipped with everything you need to split a drink with friends. The flask comes with two, six-shooter tumblers that attach seamlessly to the body of the flask using a magnetic locking system—the world’s first magnetic flask built for the outdoors. Each cup attaches to the BPA- and phthalate-free stainless steel flask. The lid is equipped with a leak-proof stainless steel plug cap with a silicone seal.

This double-wall vacuum-insulated flask holds 750mL—enough to hold an entire bottle of wine, whiskey, or your spirit of choice. Its leak-proof design also means you can pack the flask anywhere without worrying about your hiking clothes smelling like rum.

Best for Whiskey: BruMate Liquor Canteen

BruMate Liquor Canteen

Brumate

BruMate’s bold canteens come in a range of statement-making patterns, from shimmering rose gold to funky tie-dye to black and white marble. Though the patterns look contemporary, this design is modeled after war-time gasoline cans, giving it a distinctly retro aesthetic.

The flask features a drop-proof silicone cover and a lid secured via a bendable silicone attachment. Each flask stands 6 inches high and holds 8 ounces of liquor. The brand’s line of flasks (along with its other products) is made of BevGuard technology that moderates temperatures—making it perfect for toasty or frigid conditions. BevGuard also prevents the metallic aftertaste that's often found in stainless steel flasks, meaning the metal won’t leech or taint your drinks. If it does, send the flask back—the brand guarantees a lifetime warranty.

Good to Know:

Be cautious of the flasks you purchase. Many are made in bulk, constructed with cheap metals that don’t meet food safety standards. Paying a little extra can go a long way, and look for stainless steel: an inexpensive alloy that is corrosion-resistant and lightweight.

Best for Gifting: Williams Sonoma Copper Flask

Copper Flask

Many classic flasks are made of copper, and with good reason: it insulates the drink, keeping the heat of your hand from impacting your beverage. Plus, copper has serious aesthetic appeal—the vintage-inspired vessel has all the design of a classic copper Kentucky flask, but without the hefty price. In particular, this copper-plated Williams Sonoma option skips the three-figure price tag of a full copper flask.

The flask's comfortable rounded shape fits easily in pockets or purses, and its affordability doesn’t sacrifice quality: the flask has a unique luster and is finished with thoughtful details, like a corked stopper. Each flask holds up to 8 ounces of your favorite libation, and a drip-free cap is attached to the body with a hinged arm. For a personal touch, get the flask monogrammed—it makes a great gifting move for a friend or loved one. 

Best Leather: Ted Baker Double Hip Flask

Ted Baker Double Hip Flask

Ted Baker

For double the fun of a regular flask, Ted Baker’s sleek, faux-leather flask contains two mini flasks. Fill each of the 3-ounce flasks with the beverages of your choice; the two flasks slip in and out of the case for easy refilling and close shut with chunky, screw-top lids. 

The durable, stainless steel flasks are kept in a smooth, faux-leather case to give it an enduring, luxury appeal. The small curved shape and slim leather casing make it easy (and stylish) to tuck into a pocket, whether it's in a suit or a hiking jacket. Even more, the flask comes in a branded gift box for easy gifting.

Best Style: Izola Flask with Canvas Carrier

Izola Red Flask with Canvas Carrier

If you’re looking for a flask with chic, modern appeal, opt for this Izola flask. The brand was founded by an NYC photographer, and it's apparent—the flasks have a unique, Brooklyn-cool air to them. 

The small stainless steel vessel is protected by the crisp, white canvas that hugs the orange (or cream, navy, or red) flask. But don’t count style over substance: the stainless steel is ultra-durable, and the canvas coating will protect the flask from scratches and scrapes. At 6 ounces, it's also the perfect size for quick nips. Of note, this flask does not come with a funnel, so consider opting for a stainless steel flask funnel.
