Carradice Super C A4 Pannier - Black - 18 Litre

I recommend this product

As a way to transport a laptop(or a4 files) and other kit for a day it’s fine, the trouble comes if you want to transport ONLY a laptop, there is no way to cinch down the size of the bag which means the laptop flops about. For my needs it’s really far too wide, but it does work, is well made and clips on and off easily.
The other design choice that’s been made is to have the pannier rail fitted quite far down the bag, presumably so it doesn’t hang down too low when mounted on a low rider- which means on a rear rack the bag sits fairly high.

I recommend this product

does what it is supposed to, keeps all my office stuff dry whilst I cycle to work.

There is enough space for a change of clothes, laptop and lunch plus a few other bits and bobs
