  • A reinvention of the traditional hip flask.

    The classic hip flask is iconic – worth its weight in gold (or bourbon). The usual shape is rectangular, with a small spout, but we believed we could create a flask that celebrates its contents in a more user-friendly, enjoyable, easy to clean and durable way. The result is the Wingback 100ml Hip. With a seamless, cylindrical design it is reassuringly robust, resilient and adventure ready. Every flask can be personalised with a laser engraved inscription on the removable base, which also doubles as a handy bottle opener. At a 100ml capacity, it’s the ultimate travel companion, designed to serve you on any journey as well it does at home.

  • Metal: Aerospace grade 316 stainless steel from Europe, CNC machined in Birmingham, UK.

    Outside surface: Tungsten carbide carbon finish applied in Cambridge, UK.

    Pouch: Oeko-Tex double thickness cotton from Poland, Europe.

    Finish: Laser engraved, assembled by hand and packaged in London, UK.

  • Dimensions: 37mm (1.47”) diameter, 127mm (5.00”) length, 180g (6.35 oz) weight

    Capacity: 100ml / 3.4 fl.oz - lid doubles as convenient 12.5ml half measure

    Engraving: Personalise your flask with an inscription of up to 50 characters on the base.

    Considerations: The Black Steel flask retains all the precision and corrosion-resistant qualities of our stainless steel version, while the tungsten carbide finish increases the surface hardness 9x. Any marks it picks up from regular use should be easily wiped away. However, the surface is scratch resistant, not scratch proof. Anything harder than the surface (diamond, some ceramics) or really aggressive use will be able to scratch it. which is why we recommend keeping it in its cotton sleeve when not in use, and carrying your diamonds in another pocket. Internally, 316 stainless steel is food and dishwasher safe and won’t alter the flavour of its contents. Before first use, give it a good wash then fill it to the brim with your favourite tonic.

Does what it says on the tin, it is the tin.

Excellent, unique hip flask

I bought one as a gift and it was so good I purchased a second for myself.

Outstanding Quality

My husband had a promotion at work and I wanted to get him a little gift to show how proud we were of him, so the 100ml black hip was just perfect. My husband was blown away by it he could see the how high the quality finish was. So thank you Alistair and the team at Wingback!

Wingback Black STeel Hip Flask

I was very lucky to receive the Steel Hip Flask as a Christmas gift from a very good friend. We both have a passion for over-engineered products, be those gadgets, accessories, skis, snow-boards, vehicles, torches, lighters or even the humble hip flask! We each own a large collection of hip flasks for our trips to the slopes, and we're always on the look out for something new and different and BOY does the Wingback fit that bill. It is INCREDIBLY well made. the engineering is superb, it's faultless!! The flask's design makes it inherently very strong and highly unlikely to leak our precious tipple of choice for those outside adventures. So as a token of my appreciation for the amazing gift I went ahead and reciprocated my friend's generosity by ordering him the Black Steel version for his Birthday! He has a love of all things "Stealth" and the Black version certainly doesn't disappoint in that area! Not only are these products amazingly well made but the staff at WingBack were incredibly helpful and the service was second to none! If you're looking for that gift that's just a little bit special look no further!! Thanks to you guys!!


Being the owner of the cash wallet I already knew that the quality was going to be brilliant before it arrived. What I was particularly impressed with is the practicality of the product as well as its appearance, it really is the perfect size to take out and about on walks, the perfect lockdown side kick.
