Okay, so this Jason Markk Repel Spray is one of those things you don't realise you need until you've got it. It's designed to keep your favourite bits looking proper fresh by creating a durable, breathable shield against water and stains. Basically, any liquid or spill just beads right off. You can use this on pretty much anything in your wardrobe – think your suede trainers, that canvas tote, even delicate knitwear. It won't leave any weird smells or colours behind because it's completely odourless and colourless. Plus, it's a good shout for the planet too, which is always a bonus.
