The best place for a hip flask is a jacket's inside breast pocket. The next best is a back trouser pocket, with the curved side against your hip. Either way, keep the cap pointing up so a loose cap can't drip. A flat 6 or 8 oz flask hides well under a blazer. A bigger one is happier in a coat pocket or a bag.
The six places at a glance
| Where it goes | Flask that fits | Good for | Watch out for |
|---|---|---|---|
| 1. Inside breast pocket | A flat 6β8 oz flask | Dinners, weddings, any day in a jacket | Check the pocket is sewn into the lining |
| 2. Back trouser pocket | A curved 6β8 oz flask | Standing around at parades and tailgates | You will end up sitting on it |
| 3. Front trouser pocket | About 4 oz | Jeans with no jacket | An 8 oz flask shows right away |
| 4. Coat pocket | Any size | Cold games and winter walks | Coats get checked and left behind |
| 5. A bag | Any size | Hikes and long days out | It is not on your body |
| 6. A boot | A long, narrow boot flask | Tall boots with room to spare | Most boots are too snug for it |
The sizes are a rough guide for a typical flat flask. Hold yours up to the pocket before you head out.
Where a hip flask rides best, from blazer to boot
1. Inside breast pocket of a jacket
This is the spot most flasks are built for, because the weight sits high and flat. The jacket still hangs straight, so nobody sees the outline of a flask. A 6 or 8 oz flask fits well here. Check first that the pocket is sewn into the lining and isn't just a slit.
2. Back trouser pocket
This pocket gave the hip flask its name, since the flask was made to ride in a hip pocket1. Put the curve against your hip and turn the cap toward your waistband. You will end up sitting on it, so take it out before dinner.
3. Front trouser pocket
A front pocket works for a small flask of about 4 oz, because a little one stays flat. An 8 oz flask is too thick for most jeans. Everyone in the room can tell exactly what it is.
4. Coat pocket
A big outer coat pocket can hold a flask of any size. That makes it the easy choice in winter. The one risk is losing it, because coats get checked, hung up elsewhere and left behind.
5. A bag
A backpack or a shoulder bag is fine for a hike or a long day outside. Size doesn't matter there, and the flask still comes along for the day, even if you aren't really wearing it.
6. A boot
People have tucked flasks into their boots since at least the 1800s2. A museum in St. Charles, Illinois, keeps the broken pieces of one that a man carried that way. A boot flask is long and narrow so it can slide down the shaft of a tall boot. It only works if your boots have room to spare. For most people, it is more of a fun costume piece than a daily habit.
Our leather flask is sized for a jacket pocket. It holds 8 oz and is made of 304 stainless steel inside a smooth PU leather wrap. It comes in a wooden case with a funnel and two small pony cups4. To match other flask sizes to other pockets, see our chart of hip flask sizes in ounces and milliliters.
Which way the curve should face
Most hip flasks have a gentle curve on one side. Museum records describe old flasks the same way, curved so they sit snugly in a pocket3. A flask that is flat on both sides sits on your hip like a hardback book. One edge then presses into you every time you move. The hollow side follows the shape of your body and lies flat against it.
So wear it with the hollow side in and the rounded side out. On your hip the hollow faces your leg, and in a breast pocket it faces your chest. If you put it in backwards, the flask rocks on its rounded belly all night long.
Flat flasks are thinner from front to back, which helps under a close-fitting jacket. On the hip for more than an hour, though, the curved one is more comfortable.
Keep the cap pointing up every time, and screw it all the way down. If it is loose, gravity does the rest, and a jacket lining is a costly place to learn that.
When to bring the flask out, and when to leave it
If you wouldn't offer a sip to the person next to you, keep the flask in your pocket. That one rule sits under all the others.
Never drink from it in a place that sells drinks, like a bar or a stadium. The same goes for a restaurant or a wedding with an open bar. A venue with a liquor license can stop you from bringing in your own bottle5. Some states go further than the venue rules do. In Texas, for example, it is against state law to carry your own alcohol into a bar with a mixed beverage permit6.
A wedding with an open bar is a good time to leave the flask in the car. An outdoor wedding in March is a different story. Guests may stand in the cold through forty minutes of photos before anything is poured. In that case, pass the flask down the line before you take a second sip.
A cold graveside is one of the few places where a flask is truly welcome. It should go around quietly, and nobody should make a speech about it.
The time on the clock matters less than the people around you. A tailgate at nine or a ski lift at ten won't raise an eyebrow. Neither will a duck blind before sunrise or the cold end of a parade route. The same flask at your desk at work is a very different story.
Fill it with something that holds up well, like whiskey, bourbon, brandy or rum. Nobody wants a warm sip of something sweet. Our list of the best drinks to carry in a flask explains which ones go wrong and why.
What the law says before you take a sip
Open-container rules are made by each state and city, and they don't all agree. The federal standard counts any container that is open, has a broken seal or is partly empty7. A flask has no factory seal, so treat a filled one as open until you know the local rule.
In a car, most states ban open containers anywhere in the passenger area8. The rule covers passengers as well as the driver. Simply having one within reach can break the law, even if nobody drinks from it7. On a drive, the flask belongs in the trunk.
On the street, the rules change from one city to the next. A rule you learned in one town may not hold in another. So look up the city's own code before you pour on a sidewalk or in a park.
Stadiums and festivals set their own rules and check bags at the gate. The Buffalo Bills, for instance, list bringing alcohol into the stadium as banned9. Breaking their fan code can lead to ejection, the loss of season tickets or even arrest.
Flying comes with two separate rules, one at security and one on the plane. Carry-on liquids must be in containers of 3.4 oz or less, so a full 8 oz flask won't pass security10. You can read the details in the FAA's packing guide for alcohol. Once you are on board, you may only drink alcohol that the airline serves you11.
This is a general guide rather than legal advice. For a stadium, a festival or an unfamiliar city, check the official website before you go.
In short, pick the pocket that fits your flask and keep the curve against your body. Offer it around before anyone has to ask. Our complete guide to hip flasks covers how to choose one, fill it and keep it clean.
Carrying a hip flask: common questions
Where do people still carry hip flasks today?
You see them most often outdoors, in places where nobody is selling drinks. Think of tailgates, ski lifts, golf courses and cold outdoor weddings. Flasks are also a popular gift, and many come with initials engraved on the front.
Can you legally carry a hip flask in public?
The flask itself is only a container, so the rules depend on what's inside and where you open it. In a car, an open or partly empty container in the passenger area breaks the law in most states7. That's true even when nobody drinks from it. On streets and in parks, each city writes its own rule.
How many drinks does an 8 oz hip flask hold?
An 8 oz flask holds about five standard drinks of 80-proof liquor. That's because a US standard drink of spirits is a 1.5 oz pour12. It's enough for a few small drinks shared among friends.
