Question 1

Will this bag fit my phone if I have a thick case or a large “phablet” style phone?**

Accepted Answer

The bag’s interior is designed for most standard smartphones up to roughly 6.5 inches in length. However, many TikTok and Reddit users have noted that phones with bulky “rugged” cases or very large models (like the Samsung Galaxy S24 Ultra with a case) can be a very tight fit. It’s best to measure your phone gently—if it’s over 6.5 inches tall, we recommend the Mission Darkness “XL” or their larger Faraday backpack for a comfortable closure.

Question 2

How durable are the zipper and seams? Will it hold up if I open and close it every day?**

Accepted Answer

The bag uses a welded seam and a metal zipper designed for RF blocking, but daily use can test its limits. Some long-term users on YouTube mentioned the zipper becoming stiff or the seam creasing after a few months of frequent use. For occasional use (carrying to work, storing for emergencies), it holds up very well. For constant “in-and-out” swapping of devices, consider a clamshell Faraday pouch with a roll-top closure for extra zipper longevity.

Question 3

Can I really trust that this bag blocks all signals, including cellular, Wi-Fi, and EMP?**

Accepted Answer

The bag is tested to block frequencies from 0 Hz to 10 GHz, which covers cell signals, GPS, Bluetooth, and Wi-Fi. For EMP protection, it provides good shielding from low-level events. That said, a few independent testers on Reddit found that extreme signal sources (like a radio tower nearby) could cause minor “leakage” through a creased area. For absolute 100% peace of mind, always fold the flap twice and ensure the zipper is fully closed. It’s a high-quality consumer-grade shield, not a military vault.

Question 4

What if I receive a defective bag (torn inner liner or broken zipper)? How does the return process work?**

Accepted Answer

We offer a 30-day return policy for defects and a standard warranty. Some earlier reviews mentioned customer service taking a week or more to process photos of damage. We’ve since streamlined the process—please email our support team with an image of the defect, and we’ll issue a prepaid return label within 1-2 business days. Refunds are processed after we receive the item back. For zipper or seam issues specifically, we also offer a no-hassle exchange pre-shipment if you contact us first.

Question 5

Is this bag really used by law enforcement and the military, or just a marketing claim?**

Accepted Answer

The bag’s material and design are similar to what some forensic teams and field agents use for temporary evidence storage, but it’s not an “official” government-issued piece of kit. What “law enforcement grade” means here is that it meets typical shielding requirements for field work—blocking signals from modifying or wiping phones during a raid. Many civilian digital forensic hobbyists and privacy enthusiasts use it for the same purpose. It’s a solid tool for situational privacy, but if you’re expecting “military combat” webbing or bomb-proof construction, this is a lightweight, flexible fabric pouch.
