All right lets talk bags! Due to the explosion of bike packing there is now shortage of bag options out there, which excites a gear/ bag nerd like me!
There are two major brands that REI sells
There is also not shortage of cottage brands out there that will make custom bags as well. Some personal favorites of mine are Roadrunner bags, Rockgeist, and Tunitas carry all.
I've been using Revelate bags exclusively for the last 5 years and they are still rocking strong! That said, I'll also recommend Bedrock bags as I have a few of those and they are equally strong, but a bit more stiff/bulky.
