The Sea to Summit Travelling Light RFID Neck Wallet is a travel wallet lined RFID-proof fabric for digital credit card / passport protection—it keeps money, passports, and tickets safe but accessible. Featuring an RFID-proof fabric lining to protect cards from the low-power signal emitted by a credit card or passport chip, its Ultra-Sil nylon exterior is lightweight and durable. The soft 3D air-mesh is comfortable against the skin, and the webbing neck strap is adjustable (fully extended strap length is 40 inches) the low-profile design can be worn discreetly beneath clothing. Featuring five pockets, including two that are zippered for passports, credit cards, and cash, the Sea to Summit Travelling Light RFID Neck Wallet measures 5.3 x 8.3 inches and weighs 0.09 pounds. (Note that RFID-protected products only offer protection against scanning of the very low-power signal emitted by a credit card or passport chip; they will not block a higher power radio signal such as a Smartphone or a Car-Key or Garage remote.) Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
