Brenthaven's new laptop sleeves and cases are offered with a threefold "zero impact" claim.

The first claim relates to your notebook with Brenthaven's "superior protection systems" which cradle your computer from damage, meaning no untoward impact on your machine.

The second is all about zero impact on your health because Brenthaven's lightweight cases and ergonomic designs claim to make it comfortable to carry heavy loads.

And the third is zero impact on the environment because, through the company's sustainable practices, Brenthaven offsets any impact the company's products have on the environment with carbon credits.

The Eclipse sleeves, Trek sleeve and Metrolite 2 range of cases comes in a variety of colours including steel blue, burnt orange, jet black, pink and avocado.

Prices are from £59.95 for a Metrolite and the sleeves start at £24.95, available now.
