The last backpack we saw designed specifically to carry odd-shaped items was the Sherman, by Chrome Industries. Sadly it's been discontinued.

German manufacturer Red Rebane, which makes bags for bicyclists, is stepping into the breach.

Their EXO MAX bag has a simple design and a robust construction. Two Cordura flaps are connected by adjustable straps, allowing the bag to transport larger items.

It can hold unwieldy packages, tool cases, a case of beer and even guitars, though the maximum weight rating is just 10kg (22 lbs).

It also features shoulder straps, allowing you to wear it backpack-style.

The EXO MAX has been successfully Kickstarted, with 18 days left to pledge at press time. The $160 bag is scheduled to ship in July.
