MULVINNIE Faraday Bag Set, 5-Piece Signal-Blocking Pouches — Water- & Fire-Resistant, Double-Roll Closure

MULVINNIE Faraday Bags are a five-piece set of signal-blocking pouches designed to shield laptops, tablets, phones, key fobs and small electronics from wireless signals and unauthorized scanning.

These Faraday pouches combine a silicone-coated fiberglass layer with a dense shielding fabric to create a lightweight, foldable barrier against WiFi, cellular, Bluetooth, GPS, RFID, NFC and other RF transmissions. The kit includes multiple sizes so you can secure everything from a large laptop or documents to car key remotes and passports. Built for everyday use, the pouches feature a double-roll closure with hook-and-loop fasteners, plus water- and fire-resistant materials that increase durability in everyday and travel situations.

How do these pouches block signals and protect privacy?

The MULVINNIE Faraday construction uses conductive layers that reflect and absorb radio frequencies, stopping signals from entering or leaving devices stored inside. This reduces the chance of tracking, remote access, or unauthorized data reading from RFID chips and key fobs.

• Multi-layer shielding fabric blocks WiFi, cellular, Bluetooth, GPS, RFID and NFC signals
• Conductive silicone-coated fiberglass enhances signal attenuation and durability
• Double-roll and hook-and-loop closure minimizes gaps that could leak signals
• Suitable for devices with passive wireless identifiers like AirTags and RF key remotes

Which sizes are included and what fits in each pouch?

The set contains five different sizes to cover a broad range of gear and personal items. Each pouch is labeled by approximate folded or open dimensions to help you choose the right pocket for laptops, tablets, phones, cards, keys and small electronics.

• Oversized pouch (16.93" × 15") — fits laptops, large documents, magazines and GPS units
• Large pouch (13.19" × 10.39") — fits tablets, full-size phones and portable radios
• Medium pouch (10.83" × 7.99") — ideal for smaller tablets and bulkier phones
• Small pouch (folded 8.07" × 4.84") — holds watches, cards, passports and cash
• Key fob protector (folded 5.71" × 3.78") — designed for car key remotes and transponders

Are these pouches durable and suitable for travel or outdoor use?

MULVINNIE pouches are made from materials chosen for resilience and protection. The silicone-coated fiberglass resists water and increases fire resistance, while the shielding cloth stands up to repeated folding and handling, making the set a practical choice for travel, commuting and fieldwork.

• Silicone-coated fiberglass adds water resistance and higher-temperature tolerance
• Shielding cloth resists tearing and preserves signal-blocking performance
• Lightweight and foldable for packing without losing shape or function
• Secure double-roll closure prevents accidental openings during transit

How should I use the key fob pouch to reduce the risk of unauthorized access?

Place keyless entry remotes inside the smallest pouch and seal it fully using the double-roll technique to block outward signals when the fob is not in use. For extra safety, store the sealed pouch in a different compartment or a metal-lined drawer when at home or overnight.

• Seal the pouch fully by rolling twice and fastening the hook-and-loop strip
• Test with your vehicle by placing the fob in the pouch and attempting to unlock
• Store sealed pouch away from doors and windows for added protection
• Use the larger pouches for devices you want isolated from networks while traveling

Who is this for: MULVINNIE's five-piece Faraday bag set is aimed at travelers, commuters, professionals handling sensitive information and car owners with keyless-entry systems who want a practical way to limit wireless exposure. It's also useful for anyone who wants organized, portable protection for a variety of electronic devices and documents without adding bulk to daily carry.
