The 9 Best Flasks of 2023

Best Overall

Stanley Classic Flask

4.9

View On Amazon View On Dick's View On Moosejaw.com

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 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

4.4

View On Backcountry.com

Though Snow Peak’s Titanium Curved 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.

This curved flask holds just over six shots of liquid (6.4 ounces). 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

View On Amazon View On Backcountry.com

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 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 (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.

Rabbit Stainless Steel Drinking Flask

View On Amazon View On Uncrate.com

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 750 Flask

View On 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.

Good to Know:
Be cautious of the flasks you purchase. Many are made in bulk, constructed with cheap metals. 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 Whiskey

BruMate Liquor Canteen

View On Brumate.com

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.

Best Budget

Bormioli Rocco Pocket Flask With Hermetic Lid

4.8

View On Amazon View On Walmart View On The Container Store

If you’re shopping for flasks on a budget, Bormioli Rocco makes an excellent option. It’s budget-friendly and holds a generous 8.5 ounces of liquid. 

This flask is also made with glass, which won’t take on the flavors of whatever is inside. Consider this flask a great option if you’re infusing spirits, or, use it for olive oils or other liquids in the kitchen. The swing bottle stopper provides a strong, leak-proof seal. 

Expect durable quality—the brand is known for making reliable glassware for bars. Of note, since this flask is glass it will make it prone to breakage if you’re tossing it in a hiking pack or picnic basket. Another downside is it is quite heavy, so it will be hefty to carry around.
