Brenthaven could be accused of being over-protective, such is the amount of firm, thick padding that prevents laptops stored in its bags from being damaged.

Particular attention is paid to the delicate edges of notebook computers entrusted in its Edge and Edge II sleeve. The protective cases fit 14in and 15.4in laptops, respectively, and can be used to add a bit of protection when carrying your computer from place to place, or to add extra padding to an notebook bag.

A plastic slipback lets you stash paperwork separately so it isn't scrunched up as you slip your laptop into its sleeve.

The Brenthaven Edge I and Edge II cost £49.95 each from the Apple Store or direct from the manufacturer.
