I was prompted to write this review because of the previous reviewer passing out incorrect information, at least with the version of the PRO MICRO WP bag that I have. Contrary to the previous reviewer, mine does have a Molle grid which will take the Tablet bag that SW Motech sell. You simply slide the prongs on the Tablet bag, through the holes in the grid and attach the elastic "bungee" to the plastic recess (with the logo on) on the front of the bag. Although I don't have the tablet bag, I do have a small pouch attached using Velcro Molle straps. I use the pouch to keep a cloth in to keep my visor clear on my long commute (60 miles each way). See photo in case you believe the review below!

That aside, this is an excellent size which doesn't obstruct your view of the instruments or make you feel cramped in your space. The bag is small in comparison to most bags. It has an internal capacity of 4 litres. However, to get an idea of what I fit in it have a look at the photos.

In the upper clear, document compartment I have

1) 2x Emergency Urinals
2) Bike padlock key
3) Quick reading glasses case

In the inner compartment in the side elastic straps you can see:
1) Din plug to USB A & C (BMW's use din plugs)
2) Din plug to 12V cig lighter socket (for my electric pump if it discharges)
3) Hand sanitiser
4) Rubber gloves

In the divider zipped compartment:
1) Pen
2) Spare contact lenses
3) Saline solution
4) Cheap emergency ear plugs
5) "Appropriated" Salt and Pepper from McD's
6) Business cards

In the bottom divided compartment:

1) Alpine Moto earplug case
2) Wallet
3) DJI Action Battery Case
5) 26000mAh battery pack
6) Swiss Army Knife
7) Watch
8) Watch cleaning cloth, doubles as protection and cleaning specs
9) Reading glasses

In the upper division:

1) hairbrush
2) Hair pomade (prevents helmet hair!)
3) Driving glasses in case
4) Extra strong mints
5) DJI Action Cam (after removing from helmet. Normally my B&O EX earphones are there, but in for warranty claim at time of writing.)

That's a total of 27 emergency and day to day crucial items in that small bag. The zips are great, smooth and reliable. The top (outer flap) sits over the zipped compartment adding additional waterproofing. It secures with a strong magnetic closure.

I have never ever used a tank bag before fitting this to my RT. I wish I had done it sooner. I have had the bag for around 14 months and it has never leaked, the zips have functioned perfectly and it still looks brand new after 14k miles.

The handy carrying strap helps, but sometimes I clip on my water bottle carrier's shoulder strap if I have a lot to carry to the office. This allows me to sling it over my shoulder. SW MOTECH......SUPPLY A SHOULDER STRAP!! I run the strap through the carrying handle and clip the strap back onto itself (see photo).

All in all I have extremely pleased with everything my SW Motech Pro Micro Tank Bag offers. BUY IT! IT'S DOTTORE APPROVED!!

No fixing on SW 'WP Tank Bag for Molle System 4 litre'
Despite assurances from SW that the Tablet Drybag fits the Molle System, there is nothing' on the 'PRO Micro WP tank bag Waterproof 4 Litre' to keep the Tablet Drybag in place. SW did offer me a 20% reduction on a Yukon tank bag, but since I already own two micro pro tank bags, a third tank bag appears excessive. In truth I was disappointed that SW did not accept return of the 'PRO Micro WP tank bag Waterproof 4 Litre' that was unused when I first reported the issue to SW in April 2025, but apparently I had purchased the WP tank bag in November 2024 and the six month warranty had just run out. SW did offer to take return of the Tablet Drybag, but since it does fit my non-waterproof SW Pro Micro Tank Bag 3/5 litres, I decided to keep it. I was, however, surprised that in subsequent discussions SW referred to a 24 month warranty against any defect, something my complaint certainly seemed to address. As such I do feel that SW are hiding behind a legal formality and are only interested in maximising sales. Be warned. Also I am annoyed to see that SW have used a confidential email to write-up a product review - something I have never condoned, and especially so as they have awarded themselves 3 points! I am also confused that my purchase and previous review of the SW 'PRO Micro WP tank bag Waterproof 4 Litre' has somehow been deleted. To prevent SW being accused of attempting to manipulate the data shown on their website I am replacing the review.

Great tank bag. Very good quality and simple to use and fit.
