Hard Graft has recently released their 3Fold multi-use laptop bag. One of the most versatile bags to be carried around, it can be used to carry an A2 portfolio, flipped over it becomes a laptop bag which can hold two 15" laptops and when opened fully it becomes an overnighter.
This is made possible through adjusting the chestnut brown leather strap, using hooks that are traditionally used in heavy-duty hiking boots. The bag is made entirely by hand in Italy and comes in a limited edition. Available via the Hard Graft online shop and select retailers.
