Wingback Hip Flask Review: A Cylindrical EDC Flask in Tough Black Steel

Introduction

A hip flask is one of those everyday carry items most people never think about, and that is exactly what makes the Wingback Hip Flask interesting. It takes a familiar object and rebuilds it with an unusual cylindrical shape, machined stainless steel, and a finish that is far tougher than the classic pocket flask you might be picturing.

Not everyone needs to carry a flask, but for those who do, this one makes a strong case. Here is how it holds up.

Two Versions: Stainless Steel and Black Steel

The Wingback Hip Flask comes in two versions. The first is a classic silver stainless steel edition. The second is the black steel version, part of Wingback’s limited edition black steel collection with limited runs each year, which means ordering outside a production window often means joining a waiting list.

The black steel body gets a scratch-resistant tungsten carbide finish that is claimed to be about nine times stronger than stainless steel and roughly three and a half times stronger than titanium, with a Vickers hardness of around 1200 VPN. It is extremely tough, though a determined scratch is still possible, which is why Wingback includes a cotton pouch and recommends storing the flask in it when not in use.

Build Quality and Leak Protection

The flask body is machined from 316 stainless steel and is virtually seamless. The only visible seams are where the top screws off and a tiny one at the base, which exists because the base hides a built-in bottle opener. The underside carries the Wingback logo and a graphic sits inside the base.

The cap features attractive knurling for grip, and inside the neck there is a rubber gasket to keep contents from leaking out. It is also dishwasher safe, and Wingback offers a personalized inscription on the base if you want to make it your own.

Design: A Cylindrical Flask With a Wide Mouth

The most distinctive thing about this flask is its shape. Instead of the classic wide, flat rectangle with a small mouth, it is cylindrical with a virtually seamless body. That shape gives it a wider mouth than most traditional flasks, which makes filling, pouring, and cleaning noticeably easier.

Dimensions are practical for a pocket: five inches long, 1.47 inches in diameter, and 6.35 ounces in weight.

The Lid Doubles as a Measure

Beyond the main cylinder, which holds 100 milliliters, the lid doubles as a convenient 12.5 milliliter half measure. It is the kind of small, thoughtful detail you would not think to look for, but it adds genuine day-to-day utility.

Guarantee and Pricing

Wingback backs the flask with a 30-year guarantee, summed up as “try it for 30 days, keep it for 30 years.” The stainless steel version costs $158, while the black steel edition runs $231. That is a steep price for a hip flask, but you are paying for a limited edition run, an extremely durable tungsten carbide finish, and a design that looks genuinely distinctive.

Buying Advice

This is an easy recommendation for anyone who actually carries a flask and values build quality and design over price. The black steel version makes the most sense if you want the tougher finish and a limited run, keeping in mind availability can be limited and a waiting list is likely outside production windows.

If $231 feels like too much for a flask, the stainless steel version delivers the same cylindrical design, wide mouth, bottle opener base, and 30-year guarantee at a lower price.

Conclusion

The Wingback Hip Flask is a well-executed take on an everyday carry classic: machined 316 stainless steel, a wide-mouth cylindrical body, a lid that doubles as a half measure, a bottle opener in the base, and a 30-year guarantee. The black steel version costs more, but its tungsten carbide finish should keep it looking great for years. If it matches your carry habits, it is a flask worth a long look.
