This bag has been specifically designed to carry $1million in used banknotes, because why not

A US consultancy firm has created a bag which has been specifically designed to carry $1m (£650,000) in used banknotes.

The "1M Hauly Heist" can also block out radio frequency tracking - meaning it can store mobile phones and other electronics equipment without anyone knowing where they are.

There are times when you want to know exactly where your cash and other valuables are and times when you want to ensure no-one else does.

SDR Traveller, the San Francisco-based "design and strategy" company which came up with the design, said the idea of the bag came about because of the "ad-hoc" system it had been using to transfer cash from its studio to its field teams.

The company is an offshoot of Studio D - a firm which specialises in "discreet international research, design and strategy services to multinational clients with a global remit".

A spokesperson told Quartz via email:

We’re a little coy about the testing of the money bags and the Haulys. Suffice to say that they’ve been with us, in-field, in all the situations that you might imagine… [The bags] were originally designed for field work, and a specific client/project.

Available online for $720, the bag can also "accommodate carabiners and other attachments if hands-free movement is required" - and one of its special features is its ability to glide across a marble floor...

Other bags in the range include the 10k, 100k and 400k, which, yes, are designed to specifically carry $10,000, $100,000 and $400,000 respectively.

If it relates to the discreet carry of volume cash, at some point in the last year, we’ve tried it. Our workshop looks like the aftermath of a heist.
