Regardless of whether you're looking for a flask to keep hot drinks toasty, cool drinks chilled, or your favorite liquor at your hip, you'll find no shortage of options to consider. The market is teeming with flasks of almost every size, appearance, and purpose in the book. As you'd expect, the quality is as variable as everything else, with the good, the bad, and the ugly represented in equal measure. If you want the best of the best, check out our pick of the 10 best flasks around.
10. GSI Microlite Insulated Flask
If you're in the market for a slimline, durable flask that won't kick up a fuss at being knocked around in a rucksack, the Microlite Insulated Flask makes a fine choice. According to GSI, the bottle is a third lighter than other bottles of the same size but holds up to 25 percent more liquid. The vacuum insulated, 2mm walls will keep coffee and tea hot for 18 hours and cool drinks chilled for a very impressive 32 hours. The durable strap that keeps the lid affixed to the bottle provides excellent leverage for easy unscrewing - a huge selling point on cold or rainy days when your hands are slippery or frozen. An inner silicone lip guarantees that the bottle is completely leakproof.
9. Viski Metal Flask
Flasks might be functional, but that doesn't mean they can't be pretty too. The ultra-shiny coating that's been applied to the Viski Metal Flask gives it a mirror-like appearance that leaves the competition for dust. This is no case of style over substance, though: thanks to its durable 305 stainless steel construction, it's incredibly durable, and unlike certain other flasks, won't taint the flavor of the contents. Its six-ounce capacity might rule it out for sharing, but if you're looking for a small hipflask that does the job and looks good as it does it, it's ideal.
8. High Camp Firelight Flask
If you're a fan of camping exhibitions or hikes with family or friends, the High Camp Firelight Flask could be your ideal companion. It comes with two, six-shooter tumblers attached to the flask via a magnetic locking system, making it incredibly handy for sharing a drink with a crowd. The flask itself is made from durable, BPA-1 and phthalate-free2 stainless steel. Thanks to the leak-proof stainless steel plug cap, you don't have to worry about any spillages.
7. RBT Stainless Steel Drinking Flask
Named as one of the best flasks around by gearpatrol.com, RBT Stainless Steel Drinking Flask is ideal for people who either don't like to share or like to take a quick nip in the kind of places they probably shouldn't. Thanks to the silent open cap, it can be opened and closed without anyone but you knowing. The sleek, matte design and gold-tone accents are extremely presentable, while the stainless steel construction stops any unwanted flavors from leaching into the contents. A leak-free lid lets you carry it around in your pocket without any hassle.
6. Primus Trailbreak Vacuum Bottle
The Primus Trailbreak Vacuum Bottle has been designed for the rugged adventurer in mind, so even if you only intend on taking it as far as the local park, you can be guaranteed it won't let you down. It's sturdy but not bulky, making it easy to chuck into a backpack. The slightly textured surface makes it easy to hold onto if your hands are wet, while the groove on the two stoppers ensures excellent grip. You can either drink straight from the bottle using the click-close stopper or use the accompanying stainless steel cup that screws on over the stopper. Drinks stay warm for an impressive 8 hours.
5. Snow Peak Titanium Curve Flask
The Snow Peak Titanium Curve Flask might be one of the most expensive flasks on the market, but it's worth every cent of its $150.00 price tag. Made by hand in Niigata, Japan, using age-old techniques, this curvey, sleek stunner has looks to kill. It's no slouch when it comes to function either. Despite weighing just 2 ounces when empty, it can hold up to seven fluid ounces, while the premium grade titanium construction makes it virtually indestructible. As titanium doesn't retain the flavor of its contents, there's no chance of your beverage taking on any unwanted flavors. If you needed any more reason to justify the splurge, each flask comes in a very appealing custom gift box and includes a synthetic leather case and a replenishing funnel.
4. Hydro Flask
The Hydro Flask is designed like a thick, bulky water bottle. Crafted from premium-grade stainless steel, it'll keep cool drinks cold for up to 24 hours and can hold a very substantial twenty ounces of liquid, making it perfect for longer trips (if you prefer a sleeker, smaller option, it also comes in twelve-ounce versions).
3. GSI Outdoors Boulder Flask
If you're hunting for a lightweight flask that's designed to withstand any activity and any terrain, you won't be disappointed with the GSI Outdoors Boulder Flask. Small enough to fit in a wallet, tough enough to take some knocks, and substantial enough to hold 10 ounces of liquid, it's the ideal accompaniment to outdoor adventures. Although it has all the aesthetic appeal of a glass flask, its durable, shatter-resistant resin construction and silicone bumper make it virtually impervious to damage. The graduated measuring marks are a nice touch, as is the clear exterior that lets you know exactly how many more sips you've got left before running dry.
2. Klean Kanteen Insulated TKPro Flask
Few flasks manage to combine style and functionality quite so well as the Klean Kanteen Insulated TKPro Flask. Its insulating capabilities are extraordinary, with the result that cold drinks will stay iced for a stonking 92 hours. Its heat retention properties are equally excellent, making it a great option for coffee and tea lovers. The easy-screw lid doubles as a cup, with the flask offering up to around three large refills. The steel construction is food grade 18/8, so you don't have to worry about it imparting any unwanted flavors to the contents. Although it's designed as a practical piece of kit, it looks the business too, with a classy black matte coating that contrasts perfectly with the stainless steel of the inner screw lid.
1. Stanley Classic Flask
Liquor.com calls the Stanley Classic Flask "as quintessential a canteen as you can get," which is exactly what it is. Made from 18/81 rugged stainless steel, it's ultra-durable, with a sturdy body that can easily hold up to 8 ounces of liquid. The double-wall vacuum insulation keeps the contents cool regardless of what the weather's doing outside, while the inbuilt never-lose cap is a very welcome addition. It comes in a choice of designs, including Polar white, matte black, and retro Hammertone green. Well designed, expertly made, and supremely affordable, it's the perfect way to transport your liquor.
