The 100ml Hip by Wingback

The hip flask is iconic. A gentleman’s most trusted travel companion, worth its weight in gold (or bourbon). The classic rectangular shape and small spout hit popularity in prohibition, but we believed we could create a flask that celebrates its contents in a more user-friendly, less leaky, easier to clean, more durable way. 

With a seamless, cylindrical design, the Wingback hip flask is robust, resilient and adventure ready. At a 100ml capacity, it’s the ultimate travel companion, designed to serve you on any journey as well it does at home.

I hope you like the project. 

As always, your feedback in the comments section will help guide us in making quality items that will be cherished for years. Please let us know your thoughts on the design (and your favourite hip flask contents so we can put them to the test).

The Details:

  • 100ml/3.4 fl.oz. capacity and a weight of 180g/6.35 oz.
  • Include your own personalisation on the base of the flask. Just select one of the inscription rewards on the right.
  • Manufactured to aerospace standards in the UK, from food grade 316 Stainless Steel, sourced from Europe, that will not alter the flavour of its contents.
  • A large lid and removable base makes filling, drinking and cleaning simple.
  • The lip detail has been designed to give the perfect pour. Whether for a drip to taste or to pour a decent measure, you won’t get any spillage.
  • Includes a lip detail on the base of the flask that serves as a handy bottle opener.
  • Unbroken cylindrical design to eliminate risk of leakage and seam splitting.
  • Hermetically sealed with a silicone washer and a bespoke dual contact seal to eliminate leaks.

Design and Functionality

Standard flasks are about as seaworthy as a leaky boat. They’re typically made from sheets of metal that are then formed and soldered together. This leaves weak points that can split, meaning you end up wringing out your jacket just to get a taste. They are also incredibly difficult to fill (even with a funnel), their contents glugs out when you’re trying to take a sip, and are basically impossible to clean.

Addressing these functionality issues shaped the design of The 100ml Hip. We eliminated the seams with an unbroken cylindrical design, CNC machined from stainless steel for ultimate precision and strength. It’ll still slip into your pocket and will probably last longer than you will.

A large lid and removable base makes filling and pouring mess-free, and every nook and cranny can be easily cleaned.

At a capacity of 100ml and weighing in at 180g, our flask is large enough to share a sip between friends but small enough to carry with you for your whole journey. And as a little bonus, we added a lip detail on the base of the flask that serves as a handy bottle opener when you need to crack open a beer.

Personalisation

We've left some space on the base for you to add your own personalisation. Each unpersonalised flask will read "FOR YOUR JOURNEY". If you choose a personalised option then you can replace this text with your own inscription of up to 50 characters.

Include personalised message of up to 50 characters. Non-personalised flasks will read "For your journey"

Our Materials

We decided to make our flask from 316 stainless steel. With an elastic modulus of 200 GPa. It is incredibly strong, robust and highly corrosion resistant to acids, alkalis and chlorides. It will confidently withstand almost anything you can throw at it without ever losing a shade of its original glory. Along with the food-safe seals in the lid and base, all parts are dishwasher friendly and will not alter the taste of your drink.

Engineering

Our metal designs are custom made from start to finish and we're proud to make this product in the UK. A solid block of stainless steel is CNC machined to produce incredibly precise parts which are a pleasure to use. Each one is individually inspected and tested to ensure it will withstand the test of time. Our manufacturing partner make predominantly aerospace components and have BS EN AS 9100 accreditation.

Each part is measured with a CMM machine to check that each part will fit together perfectly.

About Wingback

An independent design studio founded in 2014 and based in the heart of London, we stand for an alternative to mass production and disposable culture. Everything we make is designed to be a pleasure to use, to improve with age and become a cherished item passed down through generations. 

Uniting the precision of modern manufacturing with the longevity of traditional handmade design, we create exceptional items in the UK, designed for any journey, from commutes through the capital to adventures along the Jurassic Coast.

Useful, enduring and iconic, Wingback products represent hundreds of hours of design, manufacture and testing in the field. Each one is unique, made from exceptional materials and an attention to detail you can see, smell and feel.

We're back on Kickstarter, where the Wingback journey began in 2014, because we need your support to make the custom tools and purchase the initial material stock that will allow us to make The 100ml Hip a reality. From an engineering perspective, it has been quite a challenge designing this to a reasonable cost while including all of the features that set it apart from your typical flask.

Risks and challenges

With three successful Kickstarter campaigns under my belt, fulfilling over 2,500 pledges, I have learned a lot about what to do and what to avoid and have planned this project from that experience.
We've finished the product design and engineering drawings have been sent to and approved by our suppliers so they are ready to go. We have also already made a small batch which have come out beautifully.
There is always the potential for unforeseen challenges, but my team and I have done everything we can to meticulously plan every stage of design, manufacture and delivery. Our UK suppliers and trusted shipping partners are in place to help us fulfil every order.
Please feel free to have a look at our past projects below to see our track record, and get in touch via direct message or through the comments section and I or one of the team will get back to you.
