WATERPROOF MEETS SIGNAL-PROOF.
A dry bag that blocks water. A Faraday bag that blocks signals. This is both.
The TINFOIL Dry Bag combines roll-top waterproof construction with full-spectrum electromagnetic shielding. Drop your phone, tablet, laptop, key fobs, and passports into one bag, roll the top, clip it shut — and everything inside is simultaneously protected from water ingress and signal transmission.
This is your go-bag. Your travel containment solution. Your “put everything in here and walk through the airport like a ghost” bag.
SPECIFICATIONS
Signal attenuation: ≥60 dB across 30 MHz – 6 GHz
Blocks: All cellular bands (2G–5G), WiFi, Bluetooth, GPS/GLONASS, NFC, RFID
Waterproof rating: IPX7 (submersible to 1 meter for 30 minutes)
Closure: Roll-top with buckle clip — 3+ rolls for full waterproof and Faraday seal
Interior capacity: 10L — fits phone + tablet + laptop + accessories
Material: Welded PVC exterior with integrated Faraday mesh lining
Seams: RF-welded (no needle holes, no stitch gaps, no signal leakage points)
Carry: Removable shoulder strap + top grab handle
WHY A DRY BAG
Roll-top closure is the cleanest Faraday seal geometry outside of a welded metal box. No zippers to gap. No velcro to degrade. No magnets to misalign. You roll conductive material against itself three times and clip — continuous shielding contact across the entire closure line.
The same principle that keeps water out keeps signals out. Physics doesn’t care about your use case.
USE CASES
Multi-device containment for travel
Go-bag / bug-out preparation
Evidence-grade device sequestration
Outdoor and marine environments where water and signal protection are both required
Vehicle key fob storage (prevents relay theft)
Bulk document and device isolation
WHAT’S INCLUDED
1× TINFOIL Dry Bag — Faraday Edition (10L)
1× Removable shoulder strap

FIELD NOTE
The roll-top requires minimum three complete rolls for rated waterproof and Faraday performance. More rolls = tighter seal. When in doubt, roll again.
The Dry Bag is part of the TINFOIL Signal Defense line. Currently in development. Join the waitlist for first-run access.
