The tool bag for fans of Agnes Martin, Dan Flavin and Music for Airports. The Brooks Scape series is made by Ortlieb, so there are welded seams, waterproof fabric and waterproof zipper action. You can fit a gravel tube, 2 tire levers, a small multi tool and that’s about it. It’s not gunna fit your huge cell phone, or your car keys and a tube, or a banana (unless you smush the banana into a plastic bag and jam it in there all wompus like). Very easy install. Dropper friendly. Goes on, kinda disappears, but if you do catch a glimpse, it’s not one of those saddle bags that makes your bike look sad, like a daggling old man ear lobe. It’s trim and sparse, unadorned but vibes quality. If it was a book, it would be a hardcover coffee table book about white cubes.
