Our Top Picks
Why it’s Great: I love this flask for a number of reasons. For starters, it has a silicone sleeve for easy gripping that comes with a window for seeing what’s inside the break-resistant glass underneath. That way, you’ll never overpour, know it’s clean, and most importantly, know how much is left so you can re-up as needed. Each lid is secured with both cork and a silicone liner, plus every purchase comes with a funnel. And while looks aren’t the most important thing, I happen to find this one to be unique, modern, and attractive.
How to use it: To fill up, unscrew the cap and place the smooth pour funnel over the mouth hole. Easy peasy.
Flaws but not dealbreakers: I really wish the lid was attached to the flask, so be careful not to lose it when you take a sip.
Capacity: 3.4, 8 oz | Colors available: 7 | Material: Glass, silicone
Why it’s Great: You get two great products here for a low price, both a 12 oz and an 8 oz, depending on how much drink you want to bring with you. Each flask is made from matte black food-grade stainless steel, which is very high quality. You don’t have to worry about it breaking down or leaking because it’s anti-corrosion, anti-rust, and leak-proof. Plus, it comes with a funnel, which is great because it has a small mouth hole.
How to use it: Drinking from this flask is super easy because the cap is attached and you don’t have to worry about losing it or dropping it.
Flaws but not dealbreakers: Small mouth holes make things a little harder to clean. Be sure to fill up with water and either vinegar or a little bit of soap, shake, and rinse thoroughly. Allow plenty of time for the inside to dry.
Capacity: 8 and 12 oz | Colors available: 1 | Material: Stainless steel
Why it’s Great: Now this is the flask to buy for all the guys on your bachelor trip. They come in 14 different colors, so sticking to the theme or color scheme is easy. Each flask is made from powder-coated stainless steel with an attached screw-down cap. It’s leak-proof, and because it’s attached, you won’t ever lose it. Also happens to make an easy affordable stocking stuffer.
How to use it: Because it is powder-coated in stainless steel, it’s not going to have the best grip. However, the size and shape are perfect for fitting snugly in your hand, so that shouldn’t be a problem.
Flaws but not dealbreakers: I sure wish this one came with a funnel, but it’s just as easy to purchase an affordable one on Amazon.
Capacity: 1 Ltr | Colors available: 3 | Material: Stainless steel
Why it’s Great: You can never go wrong with a stainless steel flask, especially if it comes in a pack of three for sharing with friends. By the looks of it, this is what I think of when I think of a classic flask. This one is laser-welded for solid, leak-proof construction so you never have to worry if it’ll break or spill. But if it ever does, you’ll be happy to know each purchase comes with a lifetime warranty.
How to use it: Because of the easy curve and solid 8 ounce size, it fits easily in the hand for taking a swig.
Flaws but not dealbreakers: One reviewer noted that when screwing on the cap, be sure the line threads up or you’ll lock the cap on and need pliers to remove. Sounds personal!
Capacity: 8 oz. | Colors available: 1 | Material: Stainless steel
Why it’s Great: These days, Stanley is known for those big water tumblers everyone seems to be drinking out of, but they also happen to make pretty heavy duty flasks. Because it’s leak-proof and rust-proof, this one is pretty rugged, making it the ideal camping buddy. Because it’s insulated, you can even use it for hot drinks. Perfect for the dude who needs an espresso at all times. And a great, office-appropriate gift, if your workplace happens to be dry.
How to use it: Drinking from this wide-mouth flask is pretty easy, especially because the cap is affixed to the top, so you don’t have to worry about losing it.
Flaws but not dealbreakers: It doesn’t come with a funnel, but the wide mouth does make pouring your favorite liquid pretty easy.
Capacity: 8 oz | Colors available: 9 | Material: Stainless steel
Why it’s Great: If you’re buying a flask, may as well get a funnel, too. Sure, you can pour straight from the bottle, but to prevent any spills or accidents, a handy little funnel piece makes the pouring so much easier and clean-up-free. It’s made of high-quality 201 stainless steel and it comes in at a great price point. And it’s not just for a flask, either. You can use a funnel for a variety of kitchen uses.
How to use it: Simply fix it over the mouth of the flask and pour in the liquid, holding onto the side of the flask if possible for security.
Flaws but not dealbreakers: While it definitely gets the job done at a great price, I wouldn’t say it’s the most attractive.
Colors available: 1 | Material: Stainless steel
Why it’s Great: Do you need to spend a fortune on a flask? No, but a high-quality copper flask that lasts a lifetime happens to make the perfect gift, especially for Dad, who has everything and wants nothing. Like a fine wine, the copper only gets better with age, transforming in color naturally with time. It’s wrapped in soft, beautiful leather to fit snugly in your hand. Comes in an attractive wooden box and canvas bag for storing with care. Oh, and don’t forget the attractive copper funnel.
How to use it: Before use, rinse with water and vinegar or a tiny bit of dish soap. Next, you’ll want to ‘season’ with cheap liquor by shaking and then discarding.
Flaws but not dealbreakers: Obviously, this flask ain’t cheap, so it might not be the best option if you want a flask that’s super affordable.
Capacity:12 oz | Colors available: 1 | Material: Stainless steel
Why it’s Great: If the idea of pouring your prized whiskey into a cheap flask sounds icky, then consider something more elegant and substantial. Aspinal of London makes a beautiful stainless steel flask handbound in the finest full-grain leather in a variety of colors, including, aptly, smooth cognac. It can be initialized at the top and bottom and even comes in a fancy box, making it the perfect personalized gift.
How to use it: Because of the small mouth hole, you’re going to need a funnel to fill it up. More on a solid, affordable option below.
Flaws but not dealbreakers: Unfortunately, this one doesn’t come with a funnel so you might have to make an extra purchase.

Buying Considerations for the Best Flasks
Capacity
Most often, flasks come in a variety of sizes including 3.4, 6, 8, and 12 oz. They don’t get bigger than that because then they’re too large and no longer discrete enough for your pocket, which is the whole point. Your needs should determine your size. Plan on sharing, or have a long night ahead of you? Opt for a larger size. If you’re not too picky and a shot or two is all you need, smaller should be fine. Some products on this list come with packs of two for options.
Material
The best flasks for men are usually made of stainless steel because it’s tough, typically anti-rust and anti-corrosion. It’s also durable if you happen to drop it or fall. Funnily enough, my top pick on this list is made from non-breakable glass wrapped in silicone, which carries a similar strength and durability to stainless steel. If you’re looking for an insulated option that will keep liquids at a specific temperature, check out the Stanley option.
Mouth Hole
Flasks usually come with either a small or wide mouth hole. Small mouth holes can prevent spilling, but are often harder to clean and harder to pour liquids into. That’s why it’s helpful to have a funnel that is the appropriate size. Some even come with a funnel. Wide mouth holes are easier to pour into, but can be harder to get your mouth around. Wide-mouth flasks also often come with a funnel. If you have a preference, pay attention to the size before purchasing.

Final Verdict
The best flasks are made from either stainless steel or glass and silicone for durability, and they should come in either a single-shot or double-shot size. My top pick for the best flask is Ragproper Modern Glass Hip Flask because it is durable, comes at a great price, is made from unbreakable glass, and comes with a window for knowing exactly how much liquid is inside.
