To help you find the best flask for drinking liquor on the sly, we have tried out a multitude of top products, preferring items from heavy duty and durable components, such as stainless steel, and those with plenty of room for eight ounces of liquid.

The best product we tried was the Top Shelf Stainless Steel Flask, which features an aesthetically pleasing stainless steel design and a screw-down cap that is attached to the item itself, so it cannot be lost. We also liked the fact that it comes with an easy pour funnel, for adding liquor, and that it ships with a lifetime warranty.

Award: TOP PICK
WHY WE LIKE IT: A stainless steel design that boasts a classic look, with a cap that is actually attached to the flask itself, so it can’t be lost. Plus, there is a lifetime warranty and an easy pour funnel, for the adding of liquor.
The Top Shelf Stainless Steel Flask is a high quality item made from durable stainless steel, offering an aesthetically pleasing design that has been laser welded to provide a leak-proof seal. The cap is actually attached to the flask itself, so it cannot be lost, and it ships with an easy pour funnel, making efficient work out of adding liquors. We also loved the lifetime warranty on offer.
Though the food grade stainless steel used during the manufacturing process is of a good quality, the item can dent if dropped from a high enough altitude, so be careful. Additionally, the classic stainless steel design may not suit the tastes of every consumer, as some products on this list boast unique and memorable modern designs. A flask is one of the best wine-bar accessories you can take with you.
Award: HONORABLE MENTION
WHY WE LIKE IT: Ships with a multipack containing 6 individual flasks, each featuring a matte finish that resists fingerprints and coming with caps that are attached to the flasks themselves, a feature in line with our top pick.
This Gifts Infinity 8 oz Hip Stainless Flask set is a multipack containing six individual eight ounce flasks, totaling 48 ounces of available real estate. Each flask is made from durable stainless steel with a matte finish that resists fingerprints, maintaining a clean look, and each features the same screw-down attached cap as found with our top pick, so these caps are next to impossible to lose.
It must be noted that this multipack does not ship with funnels for the pouring of liquor, despite pictures indicating otherwise. Also, these flasks are not individually boxed, so if you plan on giving them out as gifts you should purchase some gift boxes. For your needs at home, try the best wine fridge to keep wine chilled.
Award: BEST LEAK-FREE DESIGN
WHY WE LIKE IT: Reliable leak-free design, with each flask individually performance tested, with an attractive black matte finish, while being available in multipacks of 6, like our number 2 pick, or for single purchase.
This YWQ Hip Black Matte Flask is certified to be absolutely leak-proof, with each individual unit undergoing a series of performance tests. Thes flasks feature an attractive black matte finish, while being manufactured using food grade stainless steel, and are available for single purchase or in packs of six units at once, the latter being particularly budget-friendly. We also liked the attached cap, a feature in line with our top picks.
Though these are well made items, they only come with a two year warranty, which is significantly less than the lifetime warranty that comes with our top pick. Additionally, though each flask ships with a funnel, intended for the pouring of liquor, we found the funnel that ships with our top pick to be a more user-friendly design.

Award: BEST WIDE MOUTH
WHY WE LIKE IT: Wide mouth design, available in several color options, manufactured with BPA-free stainless steel and coming with an integrated lanyard cap, which is attached and, thus, cannot be lost.
This Stanley Classic Easy Fill Wide-Mouth Flask is made from BPA-free stainless steel, which does not rust, and is available in several unique color choices. The wide mouth is also extremely useful, as it allows for easy drinking and easy pouring, and the integrated lanyard cap is attached, a feature in line with our top picks, so it cannot be lost. Stanley is also an American made flask company, dating back to the early 20th century.
Though the wide mouth design is extremely useful, it does not come with a funnel, which would make pouring liquor even easier. Also, the steel is on the thinner side, compared to our top picks, so be careful not to pour in chilled liquids, as it will cause the item to sweat. It is, however, the slimmest of the bunch on our list, making it more pocket friendly. The best coolers will also help keep your drinks cool in the summer.
Award: EXCELLENT COLOR OPTIONS
WHY WE LIKE IT: Food grade stainless steel design that is available in multiple colors, including various leathers, with laser welded joints that help resist leaks and ships in an attractive gift box.
This Primo Liquor Stainless Steel Flask is a high quality product made almost entirely from food grade stainless steel, with a thicker-than-average frame, .6mm, that is appropriate for engraving. The joints have been laser welded, which helps to reduce the chances of leaks down the line, and the whole thing ships with an easy pour funnel and an attractive gift box, both features being in line with our top pick. We also liked the many color and design choices on offer.
Though the included easy pour funnel is great, this item does not ship with an integrated cap, so it could be lost if you are not careful. Additionally, this product is the heaviest flask on this list, weighing nearly 13 ounces. Wanna make mixed drinks instead? Then check out the best blender and the best blenders for crushing ice.
Award: USA PATRIOTIC DESIGN
WHY WE LIKE IT: Extremely easy to grip, thanks to being covered in faux leather, with stainless steel innards and a unique American flag design, while being one of the lighter items on this list, at just 7 ounces.
This Outzie American Flag Flask features an easy-grip faux leather design that reduces the risk of accidental droppage. The unique American flag illustration on the exterior is neat and we also liked the light form factor, as it weighs just seven ounces, making it perfect for pockets or purses. This product also comes with a lifetime warranty, a feature in line with our top pick.
Though this is made from high quality stainless steel, it isn’t quite food grade so it can change the color of your chosen liquor if left unattended in the flask for more than 12 hours. Also, the cover cannot be removed, if you tire of the design, and it is not available in other colors. You may also like the best home brewing kit.
Award: BEST GIFT
WHY WE LIKE IT: Ships with easy pour funnel and 3 small 0.5 oz cups, with the flask being manufactured with stainless steel and covered in ultra-durable PU leather.
This Gennissy Stainless Steel Flask is actually a gift set, containing one eight ounce flask, three serving cups, 0.5 ounces each, and one easy pour funnel. The flask is made from stainless steel and covered in thick and durable PU leather, making it difficult to accidentally drop mid-drink. The design is leak-proof and highly fashionable, thanks to the aforementioned leather exterior.
Though this set does include a number of useful accessories, it does not ship in a gift box, so you’ll have to purchase your own if you are looking to give this as a present. Additionally, the cap is not an integrated design, so you could lose it if you aren’t careful. Now, for when you have had too much alcohol, you’ll need the best coffee maker.
To help narrow down to the above list, we focused, first and foremost, on the amount of alcohol that can be contained in these flasks, only choosing products in the industry standard size of eight ounces, though shapes and weight do vary considerably from product to product. We also liked items made from durable stainless steel, often food grade, that has been professionally welded so as to reduce the risks of leaking.
We tended to prefer flasks with integrated lanyard caps, which are physically attached to the product itself and minimize the chances of accidentally losing said cap. To make the pouring of liquor easier and more efficient, we also picked many items that shipped with their own easy pour funnels, and one of our picks comes in a convenient wide mouth design.
As far as aesthetics, we ended up picking several items available in classic hip flask designs, often with a stainless steel exterior, but made sure to mix it up with items covered in PU leather and faux leather and those that boast some kind of unique design on the exterior, such as the American flag. Finally, we loved products that came with lengthy warranties, as long as a lifetime in two instances.
