Brompton Waterproof Bag Comparison
Published at : November 05, 2021
Brompton Metro Waterproof Large vs Brompton Borough Waterproof Large vs Brompton Ortlieb bag
We had a request - could we compare the features of the Metro (the black one) vs Borough (the blue one) large waterproof bags - we thought we would throw in the previous champion - the O-bag (the Orange one)
The video started out as a comparison of features then we decided to also see how they performed in the rain
So the video has the following parts:
0:00 | Intro
1:10 | Rain test of the waterproof bags
We did an initial test - leaving the bags out on a rainy day ...
Originally (a week earlier) we were going to leave the 3 bags on the 3 bikes - it started raining (for about 5 seconds) then stopped - we were later reminded that leaving the bikes out in the rain could be seen as Brompton abuse!
So - we left them out without bikes
We are uploading an hour of relaxing rainy day Brompton bag video - with a special appearance by our friendly robin
You can see it here (complete with robin)

Even this gentle rain for an hour showed that the zip on the front of the Metro bag isn't reliably waterproof (or we didn't do it up enough!)
3:57 | Extremely wet rainy day ride test
Then the forecast for the following day was for heavy rain - so we decided to re-do, get wet and give them a real test!
If you would like to see 40 minutes of getting wet riding around local roads - we could also upload that!
5:44 | About the three waterproof bags
6:27 | Rear pockets / storage
All three bags have two rear storage pockets - perfect for a thermos flask or bottle of water
They are all roll top so very waterproof
The Ortlieb winds here - the bags can be removed and used as smaller carry bags away from the Ortlieb mothership!
7:23 | Shoulder Strap
Metro bag - fixed
Borough bag - removable - but a bit fiddly
Ortlieb bag - removable - easily
8:38 | Borough waterproof bag features
Including:
Roll top
Webbing straps on the front for attaching .... stuff
Large (orange) interior
13 inch laptop sleeve
Zip up net pocket inside
10:23 | Metro waterproof bag features
Two fasteners on the front - with different settings
Zip pocket in front flap
Pen holders
Two pockets under the front flap
Orange interior
13 inch laptop sleeve
Zip up net pocket
11:50 | Brompton O bag features
Laptop sleeve with velcro fastener
Keyring holder
Pens holder
Two zip up pockets
Two velcro sealed pockets
13:12 | End

13:40 | Outtakes
Sorry - we went wrong on some takes!
