Our money belt is super slim with a thickness of only 0.2cm and can be worn under the clothing. So you can keep your most essential items like passport, phone, boarding pass, currency, cards, hotel, and car keys easily hidden from the eyes of pickpockets and enjoy a worry-free journey. The RFID feature in our bag protects the personal information stored in your bank cards and passports. Our waist pouch is made of water-resistant nylon which protects your documents from light rain and spills. It is however not waterproof so do not try it in heavy rain. We use premium SBS zippers, which are one of the top two zipper brands in the world. These will last a lifetime.
