Top 7 Best Flasks

  • Best budget
  • Lifetime warranty
  • Cap attached to flask
  • Some consumers may prefer a more modern look
  • Ships with only one item, whereas number 2 pick is multipack
  • Can dent if dropped

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.

#2 Gifts Infinity 8 oz Hip Stainless Flask


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.

Read Full Review: Gifts Infinity 8 oz Hip Stainless Flask

  • Multipack of 6
  • Matte finish resists fingerprints
  • Cap attached to flask
  • No warranty
  • Not individually boxed
  • No funnels included

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.

#3 YWQ Hip Black Matte Flask


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.

Read Full Review: YWQ Hip Black Matte Review

  • 100% Leak proof & matte black
  • Available in multipacks
  • Anti-rust and anti-corrosion
  • Recommended to not keep liquor in flask for more than 12 hours
  • Funnel is included, but we found it somewhat difficult to use
  • 2 year warranty is decent, but not as long as top pick

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.

#4 Stanley Classic Easy Fill Wide-Mouth Flask


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.

Read Full Review: Stanley Classic Easy Fill Wide-Mouth Flask Review

  • BPA-free
  • Most pocket friendly
  • Integrated lanyard cap
  • Plastic seal
  • Will sweat if filled with chilled liquids
  • Does not ship with funnel, despite wide mouth

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.

#5 Primo Liquor Stainless Steel Flask


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.

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.

#6 Outzie American Flag Flask


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.

Read Full Review: Outzie American Flag Flask Review

  • Best grip
  • Lightweight, at 7 oz
  • Lifetime warranty
  • Not available in other color choices
  • Cover cannot be removed
  • Can change color of liquor if left unattended for more than 12 hours

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.

#7 Gennissy Stainless Steel Flask


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.

Read Full Review: Gennissy Stainless Steel Flask Review

  • Built-in shot glasses
  • Extremely leak-proof
  • Fashionable design
  • Slight odor at first, though it faded
  • Cap is not attached
  • Does not ship in gift box

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.

How We Decided

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.

Best Flask Buyer’s Guide

The Most Important Features to Consider

  1. Size and Form Factor
    Generally speaking, flasks come with enough space for eight ounces of your favorite alcoholic beverage. There are flasks that feature more than eight ounces, or less than eight ounces, but we found that these items suffered in the form factor department. To that end, you are going to want to pick something slim enough, usually around an inch, to squeeze into a standard pants pocket or into a purse or backpack. The lighter the better, also, though not at the expense of the build quality.
  2. Manufacturing Materials
    Look for flasks that are made primarily from food grade stainless steel, as this will ensure durability and that your liquor will not become discolored or weirdly flavored inbetween drinking sessions. Items that feature leather or a matte finish on the exterior can also be incredibly useful, as they make for an easier and more efficient grip, which can minimize the chances of having an accident. Also, look for a fairly thick flask, as that could prevent damage when dropped, somewhere in the 0.4mm to 0.6mm range.
  3. Additional Features
    Flasks come with several additional features to help enhance and expedite the drinking experience. Most modern flasks boast integrated caps that are attached to the item itself, making it virtually impossible to lose said cap. Others come with easy pour funnels, which can be a boon when attempting to transfer liquor from one place to another. Still others, such as our number seven pick, come with all manner of accoutrements, including small serving cups.

Flask FAQs

What is the best material for a flask?

The most common material used in the construction of flasks is, of course, stainless steel. This allows for uncommon durability and a light and compact form factor, among other benefits. Leather flasks, however, have become popular in recent years. Other materials, such as pewter flasks made by Wentworth Pewter, have become fashionable.

Who makes the best hip flasks?

Any of the above manufacturers excel when it comes to hip flasks, but we’d be remiss if we didn’t once again mention our top pick, the Top Shelf Stainless Steel Flask. This item is nearly the perfect flask, with a light form factor, a classic design and an integrated cap. Other popular brands include Savage and Wentworth.

What is the best liquor for flask drinking?

Any hard liquor is suitable to be poured in a flask, and then later consumed. Lighter beverages, however, like wine and beer are not entirely suitable for a flask, as the ingredients used during the manufacturing process can turn acidic and slowly eat away at the interior.
