Whether you prefer sipping whiskey or another spirit, a flask lets you enjoy a drink when you’re out and about: think a nip or two on the golf course, a wee dram or a large pour while sitting around a campfire, or even a sip with a beer chaser while tailgating. These smaller vessels save space, making potent potables more portable and discreet than a bottle and cup. Flasks also make great gifts (hello, groomsmen and best men!) and heirlooms to pass down.
These days, most flasks are made of stainless steel; lesser versions of the alloy can impart a bit of unwanted flavor to your spirit, so choose a high-quality option or consider an alternate material. Ahead, the finest flasks to fill and take on the go.
Best Overall: Stanley Classic Flask
The vintage look of this flask is a throwback to the days of the thermos lunch, and the design is simple and near perfect. It fits easily into most pockets and is rugged enough to get knocked around in a cooler or backpack. Lined with BPA-free stainless steel, it’s rustproof and features a cap mounted to a hinge so you can’t drop or lose it. A wide mouth makes it easier to take a good belt from the 6.4-ounce vessel.
Best Budget: Bormioli Rocco Pocket Flask With Hermetic Lid
This glass flask from Bormioli Rocco is a nice option for those on a budget. It’s super affordable, holds 8.5 ounces of liquid, and is made of glass, which won’t impart any unwanted flavors. Of course, glass is fragile, so if you’re hiking or popping it into a golf bag or even a picnic basket, you might want to make sure to provide adequate padding to prevent breakage. The flask is on the heavier side at 12 ounces empty, but it is a large vessel that will hold about a third of a standard bottle of booze.
Best Ceramic: Misc. Goods Co Ceramic Flask
While metal flasks are typically quite durable, some variations of steel can impart a bit of flavor into any spirit they hold. A ceramic flask like this one from Miscellaneous Goods will help preserve the taste of your drink as intended when it went into the bottle. Quarter-inch thick porcelain makes this flask hefty in the hand, but that’s something you want when you’re holding 11 ounces of spirit. A cork stopper lashed in place by a leather strap keeps the hooch from spilling in your pocket or pack, so you won’t reek of booze.
Best for Outdoor Adventures: Snow Peak Titanium Flask
Titanium weighs about half as much as stainless steel. When you’re backpacking, every ounce counts, so a flask made of this lightweight metal is worth considering. Titanium is also “flavor-resistant” so it won’t taint your tipple with unwanted metallic notes. This one from Snow Peak holds 5.8 ounces and weighs a scant 3.2 ounces empty. Made in Japan, it comes with a nice pouch you can use to prevent scratches and a funnel for filling it up with your preferred hooch.
Best for Fishing: Orvis Fish Flask
For those who like to take a nip while fishing or drinkers who just dig the aesthetic, Orvis offers this lovely flask that features a sculpted fish. The piece, which is made from pewter in Sheffield, England, holds 2.5 ounces of spirit and measures 5.25 x 2.25 x .75 inches. It’s a handsome piece for any collector, and for fans of personalization, Orvis offers personalized engraving for a small fee.
Best Gift: Barbour Hip Flask
Not only is the Barbour's tartan wrap stylish, but it also makes gripping the flask a little less slippery. While tartan is traditionally Scottish, you aren’t limited to storing single malts exclusively, and the leather-trimmed design will please even the pickiest of recipients. A 6-ounce capacity makes this vessel perfect for pocketing a few nips, and the hinged arm prevents the cap from falling off or getting lost.
Best Insulated: Denver & Liely Traveller
The Denver & Liely flask is both thoughtful and snazzy. It holds a full 8 ounces of liquid and is insulated, so it can easily keep a double of whatever cocktail cold on the go. Double-walled stainless steel construction gives it a rugged utility, and a carabiner lets you clip it to the exterior of a bag or backpack. The wide mouth makes it easy to sip from and clean when you make it back home.
