I needed something to take a waterproof, lock, lunch and tools with me on day rides. Something other than Sophie's old rucksack from school. Something waterproof. Something stylish.
It also needed to be small enough to not to look like I was off on holiday. The rack and panniers was overkill for anything but a short tour.
I looked at several brands that produce similar items before narrowing it down to Carradice. They are made in the UK by hand, by one individual from start to finish. Mine is made by Christine, who features in the included catalogue article about whether the names in each bag are actual members of staff.
I'll put it on the bike tomorrow and update from there...
