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

The Partner in Crime will fit laptops and tablets up to 34cm x 27cm (accounting for the lining and such).
This means it is perfect for most 15" Macbooks, and/or A4 papers, magazines etc.
It is the perfect 2-in-1 bag if you want to carry work things, though still have a versatile bag for travel or weekends.
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 Partner in Crime ...
I ordered my first bag (large laptop) many, many years ago when Mattt had a stall on St Kilda.
I ordered my first bag (large laptop) many, many years ago when Mattt had a stall on St Kilda.
I was visiting Melbourne at the time. It was delivered to NZ where I was working at the time.
I was so impressed that when needing a backpack went straight to Matt for another great bag with style, practicality and durability.
My bag (large laptop) has a Blue Fairy Wren pattern (so Australian; one of my favourite birds) and has been in constant use for many years - local commutes, interstate and overseas meetings.
It has had NO maintenance issues and still serves me well. The design is clever and functional. I note that newer models have had some changes (e.g., the outer pocket is zipped).

Durability, style and practicality.

I can take it to work everyday and then take it out on weekends and out for dinner.
It goes with me everywhere.

I do like that you can just choose the panel and then the bag and it gets made up for you.

I totally ordered at the worst time of the year when you were on a break though still happy.
I like it even more than my old mattt bag because the zipper is tougher. The design is gorgeous and I get a lot of comments on it.
I guess I’ll be back in another five years when this one bites the dust? Yes, my old bag lasted that long with daily abuse! Maybe I should buy a couple and tuck them away somewhere. I wouldn’t mind one of the smaller bags too.

I was emailing to say how happy I am with the quality and style of the bag!

Even better than I expected!
Thank you so much!

Good size, plain, functional. Good quality zip, stitching and manufacturing so it is durable.

The pattern/fabric is striking and it goes well with the clothes that I wear and strangers ask me where I bought it from.
I also love the strap it is wide enough and long enough to sit over my shoulder comfortably.
I have bought bags for (or gone halves with) about five people for birthday / Christmas presents.
