  • 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.

Hip Flask

No fuss ordering process and an exceptional product. Delivered with minimal packaging and all as anvironmentally friendly as possible.


Andrew Nash (Crewe, GB)
100ml Flask

Very pleased; everything that I hoped it would be including the personalised inscription. I particularly like the shape of the flask which is not readily identified as being a 'hip flask'. As someone who has recently taken a liking to adding a shot of Amaretto to my coffee, it is nice to do so 'incognito' without attracting judgmental looks!

Quality engineered object!

Designed to be a hip flask (and it's a beauty) but if like me you're also considering secondary use: it's a water-tight container with an internal lip diameter of 21.5mm so it'll comfortably hold/contain a solid cyclinder that is 21mm diameter x 95mm length. Sorry for the slightly random review but the internal measurements were not on the site when I was shopping. Quality engineered object/container, thanks!

Beautiful craftsmanship

I have bought several items from wingback, pens, flask and leather wallets . The level of craftsmanship and attention to details is second to none . The feeling of holding these items and the solidity is striking.
