Pelican has built the Humvee of wallets

Pelican has brought their signature protective shells to your pocket with the new G5 Personal Utility RF Field Wallet. The rugged wallet features an aircraft-grade aluminum shell that can block RFID signals and it's both crushproof and waterproof. The gasketed o-ring and snap-latch protect the wallet's contents with a vault-like seal and the inside of the wallet has an elastomeric strap and a mesh organizer to keep all your items secure.
