Frequently Asked Questions (FAQs)

What's the main difference between these three sling bags?

The key differences come down to price, security features, and capacity. Concept Global ($39.90) prioritizes security with military-grade RFID protection and anti-theft features at an unbeatable price. 

Evergoods ($99) focuses on premium materials and a lifetime warranty for maximum durability. Aer ($79) offers the largest capacity (4.5L) with sustainable materials and tablet storage. Your choice depends on whether you prioritize security and value, build quality, or storage capacity.

Do I really need RFID protection in my sling bag?

Yes, especially if you travel frequently or visit crowded tourist areas. Electronic pickpocketing is real—thieves can scan RFID-enabled cards from several feet away without ever touching your bag. 

RFID protection creates an electromagnetic shield that blocks these signals, preventing unauthorized scanning of your credit cards, passport, and ID cards. If your cards have the contactless payment symbol, they have RFID chips that need protection.

Which sling bag is best for international travel?

Concept Global's Travel Sling Bag excels for international travel thanks to its RFID protection (crucial for passport security), weatherproof materials, and compact design that works as a personal item on flights. 

The anti-theft features give extra peace of mind in crowded airports and tourist areas. While the Aer Pro Sling offers more capacity for longer trips, Concept Global's security features make it ideal for protecting important travel documents and credit cards abroad.

How do I know if my RFID protection is working?

Test your bag using your smartphone's NFC reader (most modern phones have this), contactless payment terminals at stores, hotel key cards, or transit cards. Place your RFID-enabled card inside the bag's protected compartment, then try to scan it. If the reader can't detect your card, the protection works. 

Concept Global encourages customers to test their bags this way—successful RFID blocking means your cards remain undetectable while inside. If you can still scan cards through the bag, the RFID protection isn't effective.
