Capacity, Quality, Good Looks
I have the Jumbo Jammer mounted on my Giant Stance with a 100mm rise handlebar. It fits perfect and looks like it belongs. The bag is well thought out and heirloom quality. There is a multitude of mounting configurations.
All of the day-to-day items- air pump, multitool, cable lock, spare bacon strips- go with me without scratching the surface of the Jumbo's capacity. At the end of a 'loop' I load it with a couple gallon jugs of water, a quart bottle of thirst quencher, 4 French loaves with the fixings and I'm good on groceries. All this capacity comes without the constriction and sweat of a backpack.
The bag stays put. It takes me all of 5 seconds to unbuckle and remove if needed. I ride more because I can bring the essentials with me and have plenty of room for errands along the way.

Hard Jammer
Been rocking large cordura back packs for a long time cause I like to be able to carry a ton of stuff. I initially bought the Jumbo for touring but it has replaced my main "back pack" and is now my main daily carry. Having a massive handlebar bag is a game changer! The roll top and longer straps allow it to be tightened up on the sides for lighter loads. I was a little worried this bag wouldn't fit on my drop bars that measure 14" but it fits perfectly for me. Solid material, stitching, & construction. If you're thinking about it, get that hitter bb!

LOVED THE SPACE
I spent nearly 2 months with my jumbo jammer on my handle bars and I have some thoughts. This bag is so well thought out and crafted. The amount of stuff I fit into this bag was crazy. About half of my gear for this big trip was in this bag and I never maxed it out. The bag also served as my carry-on on airplanes or as a pack for side trips off the bike. I just took a shoulder strap from a workout bag and attached it flawlessly. So the bag is really versatile too. It's also pretty waterproof as advertised! Though my clothes were all inside a drybag within it, my book and journal never got wet when it was pouring rain. Be warned: almost all the paint on my head tube is completely stripped from the bag (I don't really care but you might). If you have 700c wheels like me I wouldn't recommend it but I think 650b would be just fine. It took me a couple weeks of riding to figure out how to pack the bag in order for me to pull the cargo straps tight enough so it wouldn't rub on my front tire. Once I managed to figure it out, I still didn't have much clearance between the bag and tire. If the gravel roads or 4WD tracks ever got a little too bumpy there was no way the bag wouldn't bounce onto the tire which is probably unavoidable. The bottom is shredded but that was the ONLY place of wear on the whole bag. If I were to recommend any changes to the bag it would be to include spacers for the handlebars so the rider isn't limited to where they can grip the bars.
