Messenger bags...

scott not scot i love the fact that they have compression straps on a bag that's only 5" wide....i'm not saying this cos i make bags...but i'd save your money...you're not gonna get much in either size of those cos they're so narrow....i think you can get ortlieb bags really cheaply?....they'd be a better option...IMO

yeah that bag will sit all wrong on your back,

i was so close to getting an ortlieb mess backpack, im very glad i didnt, they look good and all but my 'heavy flow' is so good
