Stay Off the Grid: Testing the SLNT Faraday Dry Bag for Privacy and Protection
Today is seems like every device is tracking, pinging, and syncing, true privacy is getting harder to come by. Most of us carry multiple items that constantly transmit information like phones, smartwatches, tablets, car fobs, and even some wallets. And while digital privacy tools help online, sometimes the best way to go completely silent is to use a physical solution.
That’s where the SLNT Faraday Dry Bag comes in. It’s a waterproof, signal-blocking bag that promises to protect your devices from both digital tracking and the elements. Think of it as a high-tech dry bag that doubles as a digital blackout zone.
I used SLNT’s 5-liter Dry Bag on an adventure to Florida and recently on a trip to North Carolina. In two different applications, the dry bag impressed me!
First Impressions
Out of the box, the SLNT Faraday Dry Bag feels like serious gear. It’s not flashy or gimmicky; it’s built for people who actually use their stuff. The exterior is a rugged 420D waterproof nylon, and every seam is RF-welded instead of stitched. The roll-top design seals with Duraflex® UTX buckles, which are common in military and outdoor-grade packs. I also have the Waterproof Faraday Backpack from SLNT that closes the same way.
It’s lite but feels solid. The bag doesn’t look like a gadget; it looks like an outdoor essential, which I like. You could carry it through a store or strap it to a kayak, and it wouldn’t draw attention. I know, because I’ve done both.
Inside, the Faraday lining gives it structure SLNT uses its Multishield® Faraday Shielding Material, which blocks all major signals: cellular, Wi-Fi, Bluetooth, GPS, RFID, RF and even EMP interference. The interior feels like a soft metallic fabric, and the seams are precise. It’s a clean and minimalist.
Features and Design
The dry bag combines digital isolation with physical protection, which is exactly what makes it so attractive.
Complete Signal Blocking: Once your phone goes inside, it disappears from the grid, blocking all major signals. For privacy-minded folks that’s powerful peace of mind.
Waterproof and Durable: The waterproofing is top-tier. SLNT rates the bag as submersible for up to 30 minutes at a depth of 10 feet. RF-welded seams and a roll-top closure ensure a tight seal.
Size Options: Available in 2.5L, 5L, and 10L sizes with adjustable straps and optional MOLLE attachments. Organizational inserts are available separately for each. These are nice, but not necessary.
Field Test: Kayaking in Florida
I took my SLNT Faraday Dry Bag on a family kayaking trip on the Weeki Wachee river in Florida. Before pushing off, I slipped my iPhone, wallet, and a small radio into the 5L bag. I rolled it down three times, clipped the buckle, and placed it on the back of my kayak.
I am new to kayaking and was afraid that I was going to dump myself and my stuff into the crystal-clear water, but thankfully I didn’t. The bag did get splashed a lot as I paddled, panicked, and pushed down the easy-going river.
In hindsight, I should have taken a picture, but I was scared I’d flip myself trying to do so.The trip was fun, and we even glided past a manatee. Finding myself in an unfamiliar situation was somewhat stressful, but I had a lot of confidence in the SLNT dry bag.
Zipper Pocket: Some Signals Allowed
The newer bags have a zipper pouch that will fit a phone or tracker. This pouch is not RFID protected. If you still want to get calls or have someone track your progress on a hike, this pocket is perfect for that.
I think this is a great compromise that SLNT has incorporated into their bags. Sometimes we want a digital blackout, but others we still want to connected to our friends and family. This new feature is a great compromise that everyone can appreciate. The Faraday Waterproof backpack as the zipper pocket, but bigger.
Performance Testing
Signal Isolation: Calls went straight to voicemail, Bluetooth dropped instantly, and GPS froze - total blackout.
RFID and Key Fob Protection: The car wouldn’t unlock or start when the key fob was inside which great for preventing relay attacks.
Ease of Use: Sealing takes seconds and feels natural after a few tries. Lightweight and portable.
Radio Silent: Signals from a UHF/HVF handheld radio are also blocked.
Comfort and Fit: The dry bag can be adjusted for any height and is very comfortable to wear.
Everyday Use
This Faraday dry bag is perfect for outdoor adventures, travel privacy, or digital detoxes with family. It is ideal for storing passports, drives, radios, or EMP-sensitive gear. Parents can even use it as a digital timeout tool, once sealed, no one’s scrolling under the table.
