Originally created by a bike courier who sick of bags breaking sewed a bag out of the toughest material he could get, marine canvas. To this day they make somewhat indestructible, well designed, trendy well loved bags.
Also they have a lifetime warranty and repair policy that is very hard to beat. Maybe you’re not local, but you can tell these will be well made (and they really are)
