My business travel essential goes everywhere with me - and it probably isn't what you'd expect

If you're anything like me, attending multiple events each year, then you've probably refined your "mobile office" essentials. The laptop, the USB stick, the tablet. These are par for the course.

But for me, the absolute essential is my Skysper foldable hiking backpack (currently discounted on Amazon.com for $17 and Amazon.co.uk for £16). Since it folds into a neat square with carrying handle, I never travel without it.

This lightweight 10L may not be the best laptop bag you can get. What it is, though, is ultra-portable. If you're looking for a slimline bag to take around conference halls without carting around your entire wardrobe or filling your suitcase with a full-sized backpack - as I was - this ticks every box.
