Troubling your wallet a full $425 for its troubles, the Killspencer Business Messenger bag is still an enticing purchase. Sculpted from military grade waterproof fabric, it’s primed for applications in war, hunting, fishing and sailing, though it’ll handle the daily commute nicely too and fits anything up to a 17″ MacBook plus an iPad, iPhone and Moleskine sketchbook in special compartments, and a heap of stuff in the main holdall too.
