The Sea to Summit Travelling Light RFID Neck Pouch 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 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 three pockets, the Sea to Summit Travelling Light RFID Neck Pouch is large enough for a passport, measuring 4.9 x 5.9 inches and weighing 0.04 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.
