All bags have modular straps so they can be personalised and allow your bag to be worn as a shoulderbag and backpack.

The Significant Other will fit laptops (and other devices) up to 39cm x 32cm (accounting for the lining and such).
This means it will comfortably fit a 16" Macbook Pro along with A4 papers and 12" vinyl.
As it is a wider style, the internal zipper pocket is divided into two sections which are perfect for keeping passports, pens and charging cables organised.
Your bag uses modular, mix-n-match straps so you can configure your bag exactly how you like.
These are attached with custom aluminium hardware developed in-house (and lasercut locally) as there was nothing available that did exactly what was needed.
The straps are available in a range of colours and widths so you can personalise your bag now, or in the coming years.
The padded grab handle is positioned near the strap loops on the back of the bag.
This gives an easy way to hang and pickup your bag and has been sized to also slip over most suitcase handles, allowing you to effortlessly organise your luggage.
Many customers have mentioned this is a substantial improvement over their existing mattt bag/s without a handle.
Every bag now comes with a unique serial number and QR code digitally printed on a label inside the front pocket.
This allows you to view details about your bag such as the date it was made, a constantly updating cost-per-day and photos of your bag being made.
It also means if your bag is ever misplaced it is as easy as possible for someone to organise it's return through a form on the bags archive page.
Your bag is made to last - and a big part of this durability comes from using the highest quality zips.
The main zipper is a dual YKK #8 coil zipper, while all pockets use a slightly lighter weight YKK #5 zipper (shown)
As these are used in most quality bags this also means the sliders are easy to source anywhere in the world should they ever need to be replaced.

What people are saying about their Significant Other ...
Matt talked me through each of his products, and helped me decide which one might be best suited to my needs.
Matt talked me through each of his products, and helped me decide which one might be best suited to my needs.
Matt also took great care to show me all the features, and explain how they can be customised.
I like that my bag is personalised, but also that Matt makes sure each bag is up to his high standards of quality.

I just wanted to tell you I've had my mattt shoulder bag for over four years.
I just wanted to tell you I've had my mattt shoulder bag for over four years.
It served as my laptop bag which I carried to work everyday and has since doubled as my nappy bag.
It still looks great and shows no signs of it's heavy use.
My only complaint is I have no excuse to buy a new one!

It's the best solution I've found yet to the problem of what to use for carry-on baggage on planes.
It's the best solution I've found yet to the problem of what to use for carry-on baggage on planes.
I am the proud owner of three of mattt's excellent bags.
All the bags are durable, functional, and fashionable. When one bag did show signs of wear after a number of years, Matt was kind enough to repair it free of charge.
In short, I reckon mattt makes great bags!
