Waterproof wash bag with removable transparent plastic bag for frequent flyers.
With the Hanging Toiletry Kit Minimalist from Cocoon, your chances of getting through airport security unmolested increase. At least the removable transparent plastic bag makes it easier to check the liquids in your hand luggage, and there is no more space than the permitted bottle size anyway. But the wash bag is waterproof and dirt-repellent, has four compartments with water-repellent zips and a stowable hanging hook.
