(Pocket sized) Messenger bag anti-slide strap

aka the Pocket Sized Messenger Bag Spatial Orientation Stabilisation Device, or PSMBSOSD

If, like a large percentage of the population of Instructables, you wear a messenger bag and ride a bike, you'll be familiar with the problem of the bag slipping off your back and ending up under one armpit as seen below. This is a pocket-sized solution that you can quite easily make for free, or for at most a few quid. This is also my entry for the Pocket Sized competition.

Step 1: Materials

The Pocket Sized Messenger Bag Spatial Orientation Stabilisation Device, or PSMBSOSD, was inspired on one of my bike commutes to work that I could hook the strap of an umbrella in the side pocket of my bag over the strap adjuster and keep the bag in place. Having just read about the Pocket Sized competition, I pondered the idea on the ride home and came up with this by the time I arrived.

You will need:
- String or webbing, about 50cm/20" should be enough
- Two key clips (you could get away with one but it would make the PSMBSOSD slower to assemble)
- A split ring (again, not entirely essential- you could replace with a small amount of string or thread)
- A messenger bag
- Optional- a credit card sized card, sturdy business card or just a rectangle of flat plastic

- Scissors
- A lighter (if you are using synthetic string and want to seal the ends)

why not use a backpack instead?

THis could also be accomplished with a small leader running from the main strap to a clip on your belt.

and there me on me boike thinking that my messenger bag looked cool right up to the point where it turned left for me. This is one instructable I will be carrying out tomorrow

Nice fix! You could even run (or continue) another string over your other shoulder and attach it to the bag at about the same point. You would have a sort of "X" of straps over your chest. Only downside I guess is it starts feeling like a backpack.

I just don't like the way it looks. good idea though...

[Mcblugi]

well you can find materials to match your bag/ strap

[CybergothiChe]

cool, but why not just another one of those black straps that come with the bags

I'm a big guy, and I'm not sure of the physics, but I think that it's even harder for me to keep a messenger bag on my back, probably my roundish shape, lol. Your solution is simple, elegant, and effective, and bonus, it's portable and deployable. I love it!

I like it. The problem that I have more often is that when I run, the little jacket that protects your shoulder from the strap slides around. I think that could easily be solved with a safety pin, though.

Even faster: Staples.

Nice job! Bring about 50 or something, then you have a lot. :P But you don't have 50 pockets...
