SLNT Review
Military-grade Faraday bags and RFID-blocking gear with patented shielding technology trusted by Google, US Army, and Homeland Security.
Why We Recommend SLNT
SLNT stands out in the Faraday bag market by delivering lab-grade signal blocking in genuinely usable everyday gear. Their patented Silent Pocket / Multishield material achieves 85-100+ dB attenuation across wireless bands from 700 MHz to 40 GHz, effectively killing cellular, Wi-Fi, Bluetooth, GPS, RFID, NFC, and key fob signals when devices are properly enclosed. Independent testing confirms these bags actually work—calls don't come through, GPS tracking stops, and wireless hacking attempts fail. Unlike cheap Amazon pouches with questionable shielding, SLNT's products are verified by third-party testing and trusted by serious organizations.
The institutional trust signals here are substantial. Google, the US Army, and the Department of Homeland Security use SLNT products, and the company holds multiple military contracts. Their partnership with Purism—a respected privacy-focused hardware vendor—further validates their positioning in the security community. The Wyoming-based company has built a reputation on professional-grade protection rather than novelty gadgetry, which matters when you're trying to protect against sophisticated tracking, relay attacks, or evidence tampering.
Best For
Bitcoiners who take operational security seriously will appreciate SLNT gear for protecting hardware wallets during transport, preventing location tracking when visiting conferences or meetups, and blocking potential wireless attack vectors on phones that might contain wallet apps or authentication codes. Travelers moving through high-risk environments, crossing borders, or attending large events benefit from the ability to completely disconnect devices from all networks without powering them down—useful for maintaining plausible deniability about device contents or simply avoiding unwanted tracking.
Business executives, journalists, activists, and anyone handling sensitive information represent SLNT's core consumer market. The backpacks and tech organizers work as legitimate everyday carry while providing instant signal isolation when needed. Car owners concerned about relay attacks on keyless entry systems can protect their fobs in SLNT sleeves, preventing thieves from amplifying and cloning signals to steal vehicles.
Forensics teams and law enforcement use SLNT products to preserve digital evidence by preventing remote wiping or tampering with seized devices. Organizations needing standardized Faraday protection across teams can access bulk and corporate sales channels for consistent deployment.

Considerations
Complete signal blocking means losing all wireless functionality while devices are shielded—no calls, no Find My tracking, no notifications, no contactless payments. Premium pricing (starting around $50 for phone sleeves, significantly more for backpacks) may deter casual users who could manage with cheaper alternatives. Some reviewers note boxy, stiff designs and occasional issues with magnetic pocket attachments.
