Recycled laptop bags are nothing new, but the price on two freshly-launched green laptop bags is enough to turn heads.

While previous recycled bags made from esoteric materials like old sails and rubber truck tyres have commanded a price tag of £60 and up, these new Shoreline Cases clock in at just £30.

Each case is made from half a dozen 0.5 litre plastic bottles. The manufacturer says that using recycled rather than virgin material for the bags saves enough energy to power your laptop for 150 hours.

Standard laptop bag features such as pockets for peripherals and a shoulder strap are present and correct, and the bags weigh a reasonable 500 grams.

The 15.4-inch and 13.3-inch Shoreline Cases are on sale now via the Natural Collection website.
