Good-looking and practical.
The Schwalbe Tyre Bag made out of real folding tyres and truck tarp.
Schwalbe have particularly strict quality assurance with folding tyres. Tyres that are too heavy, have run-out defects, or are optically un-round are immediately segregated, but no longer immediately scrapped, rather they are processed into useful Schwalbe Tyre Bags.
A great bargain courier if you don't have too much to carry. A cracking bag for buzzing about in town, this. Put together from tyres and heavy duty waterproof polyester, it’s a simple, yet effective, courier bag with a 10 litre capacity. It’ll that’ll hold a bunch of files, a laptop (it isn’t padded) or a change of clothes. The sternum strap is swappable and the bold graphics will mark you out in traffic.
It’s impeccably behaved on the bike, and it sheds water pretty well too: 6/10 for rain resistance.
