Brompton waterproof backpack water resistance test

What do you do when you are on holiday and the weather is not its best? Grab your Brompton and the bag you have with you and check it’s waterproof credentials We already made a video on the Brompton borough waterproof backpack features:    • Brompton Borough Waterproof Backpack Graphite   but we were asked asked exactly how waterproof is it? (or is it just water resistant) so we thought we would give it a test on a cold rainy day on our holiday (so cold in fact it turned to snow!) 0:00 | Intro 1:19 | Snow test 3:08 | Snow test results 4:07 | Rain test 4:45 | Swimming pool test 5:10 | Swimming pool results 5:39 | Summary 6:20 | Outtakes
