Picked up the 22 litre back pack great little bag,wife said it looks like teenage mutant ninja turtle,comfortably holds 12 500 ml cans of beer?.doesnt shift around speed tested to 200 km.Very aerodynamic ,only complaint was lower chest strap connector is offset to avoid scratching tank .I found it awkward to latch

Been looking at Ogio's new backpacks....they offer a Mach 1, Mach 3, and Mach 5. Difference is just size, layout is the same, mostly. Two of my riding buddies just got them, and one has already gone down on the bike while wearing it and it held up well to the gravel. Sturdy build quality and nice zippers. Sleek design too, just gotta order one!

They are not that big,it's just that they seem good for the "shit I forgot to pick up this mode"tank bags are good but I if your just running around and a magnet picks up any metal pop cap beer cap whatever there goes a scratch on the tank

I always wanted one of those Ogios but the bag that my Icon helmet came in works so well as a backpack, I never replaced it. I use it every day.

I have the Mach 5 .....l really like it. No complaints
