Fed up with perilously balancing a laptop off one shoulder as you negotiate the treacherous icy conditions? You could always have your must-have business kit trundle along beside you and help you balance a little better.

Waterproof bag maker OverBoard has launched a waterproof laptop trolley bag that can also be worn as a backpack.

Made from PVC tarpaulin, the Waterproof Laptop Trolley Backpack is suitable for laptops with screens of up to 16in. A three-stage telescopic handle, that extends to 55cm, and two wheels ensure the laptop bag can be wheeled along on the ground.

The bag also has padded straps, usually kept out of the way by buckles, that allow users to use the bag as a rucksack. Simply depressing the handle and undoing the buckles frees the straps. OverBoard has also included slot-on wheel covers so you don't need to fret about the bag leaving dirty marks on your clothes.

The trolley bag's main compartment has an expansion zip, so the space inside the compartment can be increased - ideal for stowing larger items as well as your laptop.

The laptop bag also features a number of compartments and zipped-pockets ideal for storing a power cables, a mouse or even your MP3 player and mobile phone.

Priced at £89.99, the Waterproof Laptop Trolley Backpack is available now from OverBoard.
