This is the bag you actually remember to bring with you. It folds down into a neat, palm-sized pouch but expands into a seriously roomy tote that can handle a full weekly food shop or a heavy beach towel and sunscreen. The bold blue and white vertical stripes give it a classic, clean look that feels right at home on the tube or by the sea. It is made entirely from recycled plastic bottles, but the texture is surprisingly soft and smooth rather than stiff or rustly. It is incredibly lightweight to carry, with wide shoulder straps that do not dig in when you have loaded it up with heavy groceries or wet swimsuits. Inside, you will find two handy slip pockets to keep your keys and phone from getting lost at the bottom.
