Reddit mentions of Outeredge 20-inch Folding Bike Bag

I've got one of these: https://www.amazon.co.uk/Outeredge-inch-Folding-Bike-Bag/dp/B0011FERCA/ref=sr_1_7?keywords=folding+bicycle+bag&qid=1557835525&s=gateway&sr=8-7

Bad points: it's not padded

Good points: there's an internal seperator pocklet so you can pack other stuff in there and it will be clean, plus the pocket it all packs down into is available on the outside of the bag when in use. Finally as well as having a useful shoulder strap and handles, the buckled straps when the bag is folded down and in its pocket make it very easy to attach to either the handlebars or the saddle of a Brompton. Wouldn't use it for flights but for coach journeys etc it's perfect.
