15 Best Hidden Flasks (Review) In 2021

The best-hidden flasks are the ones that security will never suspect. That’s why we’ve chosen the GoPong Hidden Lotion Flasks as our Best Choice product. In this pack, you get three lotion bottles that hold 4 Oz. of alcohol each (that’s about 8 shooters in total). The reason they are so perfectly hidden is because of how convincing the lotion bottles look. For a start, they’re not known brands, so security won’t be able to spot any inconsistencies in the design. They also have added information and ingredients on the bottles to make them totally convincing. The attention to detail is what makes these some of the most clandestine flasks available. They’re made from food-safe plastic and even come with funnels, so you don’t waste a drop.

The SneakyBooks Recycles Hollow Book is a strong contender to be the best-hidden flask on the market. It’s also one of the simplest ideas – cut a flask-shaped hole in a book and put a flask inside. However, even though it’s possible to make one of these yourself, it’s much harder than you think. Cutting the perfect sized hole through hundreds of pages takes some precision tools. One of our favorite things about this hidden flask is the fact that the company used real recycled hardback books, to save them from being shredded. Not only does that make the product less conspicuous, but it also means you’re doing a bit for the environment (sort of). And, because of the size of these hardback books, you can fit a 6oz stainless steel flask inside (which is included).

One of the best ways to smuggle something past security guards is to hide it in something they aren’t likely to check. What security guard is going to grab a tampon out of someone’s bag and start messing around with it? That’s why these tampon-shaped secret flasks work so well. They’re slightly bigger than a normal tampon, so you might need to hide them with a couple more objects, otherwise, they could stand out. Each flask holds 1 Oz. (less than a shot), but there’s ten of them so you should be able to hold plenty of booze. Smuggle Your Booze with 10 Tampon Flasks and 10 Sleeves don’t have the highest-quality lids, so it’s worth keeping them upright to stop them from leaking. An amazing gift for men who love to drink.

The Soft Floppy Flasks made by Smuggle Your Booze are one of the least inventive flasks on this list. Instead of trying to come up with a James Bond-style gimmick to hide your booze, this product is just a plastic container that you can stuff into your bra, shoes, pants, or anywhere else you can find. Each flask contains 4 Oz. and it comes in a pack of 4 flasks. That means you can sneak over 10 shots past the guards. One Amazon customer made the interesting point that each bag has “Smuggle Your Booze” written in big bold letters. So, if you do get caught, there is no way of talking your way out of it. It’s not the most subtle flask, but it will do the job if you can find somewhere to hide it.

The Tipsy Tubes 8 Oz. Hidden Alcohol Flasks are bigger versions of our Best Choice product. The fact that they’re bigger means that they can hold twice the amount of alcohol (8 Oz. each, which is 16 shots in total) but it also means they’re slightly more conspicuous in your bag. The designs are still great though – you get hair paste, liquid bronzer, and sunscreen – and they should get past security without any problems. They’re made from food-safe plastic that’s free from BPA and they even back up their products by offering a satisfaction guarantee, so if you’re not happy, you can get your money back.

If you’re looking for a secret flask that works, this is one of the best. The Original Binocktails Bev-Brush Paddle Brush Secret Flask looks exactly like a paddle hairbrush. You’d have to look close to tell this apart from an actual hairbrush. You can even use it as a hairbrush. It also feels authentic because the weight is about the same. Inside the flask, you can hold 6 Oz. of your favorite tipple, which works out at about 4 shots.

On the back of the hairbrush, there’s even a mirror, which makes this the perfect 3-in-1 tool for a night out. It’s got a screw cap that works in most cases, however, some customers have complained that it leaks. Unfortunately, that is the risk you take with most of these items. You can put plumbing tape around the seal to make it work better.

10 years ago, no one would have looked twice at this camera flask. Nowadays, everyone has a camera on their smartphone, so these cameras are becoming rare. However, that means you can get this secret flask at a knock-off price. Binocktails 5 OZ Camera Flask is one of the most convincing fake-product flasks out there and looks like a portable mirrorless camera.

Holding 5 ounces of alcohol, this camera is perfect for someone who just wants a couple of swigs. It’s doubtful that you will get hammered 3 shots, but you’ll get a nice buzz. Each flask comes with a funnel to make pouring easier. However, if you’re just carrying a camera and a funnel, you might give the game away.

The BoozeBrella was one of the originally hidden flasks. Like the hairbrush hidden flask, it works perfectly because it looks and feels like the real things. Unfortunately, it doesn’t work like an umbrella. But don’t worry, because you’ll be too drunk to care!

It holds 9 Oz. (6 shots) of alcohol, so there’s plenty of capacity for one person. Like all of the flasks on this list, it’s made from BPA-free food-grade plastics. It also comes with three leak-proof seals and a funnel that makes it easier to pour. We’d say this is one of the best-hidden flasks, except for the fact that they’re quite well-known, so some security guards might be wise to it.

If you’re feeling particularly daring, you could use the Binocktails Bev-Satch to smuggle 30 Oz. of alcohol into a music festival, concert, or anywhere else. That’s 20 shots for you and your friends to enjoy (please don’t drink all 20 shots to yourself). You might be thinking: “What if they open the bag and find a plastic reservoir full of booze?”. Don’t worry, they’ve already thought of that. If they open the top of the bag, all they will find is a normal bag, full of your normal possessions. The booze is hidden in the bottom of the bag, in a secret compartment. Even the zipper is hidden, so it doesn’t look like there’s anything there at all. Not only is this one of the best hidden flasks, but it’s also one of the biggest.

The Forum Novelties Double Sided Binocular Flask is more of a joke flask than a serious smuggling tool. It’s not crazy to take a pair of binoculars to a festival or on a cruise, but there’s a chance it could raise some suspicion. Instead, they work as part of a fancy dress costume or just as a gag gift for someone. The cool thing about this flask is that it’s two separate flasks in one. Each side of the binoculars holds an 8 Oz. flasks. The only problem is that they don’t look like real binoculars up close, so an eagle-eyed security guard might catch you out.

The Wine Rack is easily one of the sneakiest hidden flasks available. It’s a real working bra that can hold up to 25 Oz. of alcohol. That’s enough to get any going! It’s quickly becoming a festival favorite because you can sneak plenty of booze into the festival and keep your boobs supported. The bra is relatively easy to fill with a funnel and very easy to drink from. It’s got a drinking tube, similar to a CamelBak, that allows you to sip on your booze without the effort of unscrewing a lid. People have used this for working out (with water obviously) and student nurses have asked if they can wear it during a shift. The only difficult thing to work out is what size you need because it only comes in small and medium, instead of coming in different bra sizes. It would certainly make a cool gift for beer lovers in your life.

If you’ve been underwhelmed by the hidden flasks we’ve shown you so far, we’ve got one last product up to our sleeves that are bound to impress. Bootleg Bottle Seal 20-Pack Accessory Kit is the perfect tool to turn your own bottles into one-time-use hidden flasks. So, if you’ve got a ton of old dandruff shampoo, sunscreen, or other bottles left over, here’s the perfect way to recycle them. You simply place the seal into the inside of the bottle lid and it will reseal the bottle. Make sure you’ve cleaned the bottle thoroughly first though, or you could end up with some off-tasting booze. There are a few complaints on Amazon about the sizing, but it could be down to people not reading the description correctly. It says they fit onto 8 Oz. and 16 Oz. bottles, but not all of them have the same size lids. If you’re not sure, choose a bottle with a smaller lid.

The best hidden flasks are the ones you’d never see coming. If you walk into a festival with a tote bag full of everything you need for the day, security will never expect there to be a hidden compartment inside. That’s exactly what the PortoVino Beach Wine Purse has. Open the zippered compartment and you’ll find a fully-lined and insulated pocket that can hold up to 1.5L of your favorite beverage. That’s about two bottles of wine that you can pour into a cup and enjoy anywhere. This is probably the most discreet way to sneak booze into a restricted area. 

Everyone needs sunscreen, right? We’re always being told to protect our skin from the harmful UV rays of the sun, so why not take advantage and hide your booze in these GoPong Sport Bottle Sunscreen Flasks. The convincing design is sure to help you get your booze past security, so you don’t have to pay over the odds when you’re inside the venue. Each bottle can take around 8oz, which means you can take a total of 10 shots with you. They’re made from food-grade plastic and come with a mess-free funnel for easy pouring. 

If you’ve ever been on a cruise before, you’ll know that alcohol can be prohibitively expensive. To save yourself hundreds of dollars, you need a way of sneaking your own booze on board. This four-pack of Cruise Runners Fake Shampoo and Conditioner bottles is the perfect way to hide it. They have a totally convincing design that contains no metal, so they won’t show up on metal detectors. Plus, they even come with security seals to keep the contents extra hidden. Each bottle holds 16 fluid ounces, which is about eight ounces.
