6. Plastic Wallet
When it comes to adding weight to a bag, a wallet is usually the heaviest item. Save yourself the extra ounces and invest in a slim plastic wallet. Many brands, like D-Armor, come equipped with RFID protection. This means that no unsavory characters will be able to scan and steal information from any of your cards inside. You really can’t put a price on convenience and peace of mind. And with the low prices of these wallets, this is a completely affordable expenditure.
