Given the recent explosion of innovative handlebar bag designs for gravel bikes, its shocking that so many manufacturers are still stuck in the dark ages when it comes to addresssing the most glaring flaw of these bags: their complete inability to provide any real protection from the elements. As things stand now, the average handlebar bag is little more than a glorified, water-resistant pillowcase that can only hope to keep its contents dry in the most gentle of rainfalls. So, I ask: what would it take for these companies to produce a handlebar bag that can truly withstand the fury of a torrential downpour, without the need for cumbersome rain covers or ponchos? Would it require some sort of revolutionary new material, or perhaps a drastic rethink of the bags fundamental design?
