Cruelty-free, luxury vegan leather brand Matt Nat made its name with bags, footwear and smaller accessories. There are plenty of delights to choose from, but this Colten flap over royal blue beauty caught our eye. It’s big enough to fit your laptop, but streamlined enough not to be bulky. The straps are easily adjustable, inside you’ll find a smartphone pocket and the folded over zipper will keep your valuables safe. Not only is it vegan but all linings are made from 100 per cent recycled materials.
