Even though you may be able to use your standard, everyday wallet for travel, purchasing a designated travel wallet can be a good idea. These are often larger than standard wallets, and sometimes offer additional security features that make them safer for use while traveling, to prevent pickpocketing. To choose the best travel wallet, begin by considering what you will need to carry in it; some people simply use a large wallet with a strap in lieu of a purse, and in that case, need more space than people who will store the wallet in a pocket or larger purse. Consider the material as well, because travel wallets need to be durable.
At its most basic level, a travel wallet should be able to accommodate a passport without bending or folding it. Not only will this prevent damage to the passport, but it makes it easier to find and access when it is needed. Space for paper money as well as coins is important as well, particularly when traveling to countries that give coins in relatively large denominations; you don't want to lose them! Consider any other travel documents you want to carry in the wallet as well, such as a boarding pass, train tickets, or other identifying papers. The wallet should have a number of pockets for storing these items.
Considering the security features of the travel wallet you are considering is important as well. If you will be wearing the wallet outside the body like a small purse, it is generally a good idea to select one with a strap so you can wear it across the body, making it much harder to snatch. If it will be inside a purse, choose a travel wallet with a clip. It can then be clipped onto something such as strap or keyfinder inside of the purse, which will also make it much harder to for someone to reach in and grab it unnoticed.
In addition, choosing a travel wallet made of durable materials and sturdy zippers is important as well, since, chances are, it will need to take a bit more abuse than a standard wallet. Leather is a good choice because it is very durable; other materials such as nylon may be less expensive, equally durable and easier to clean, however. There are many different colors and styles available to suit different tastes as well, but in general, selecting a travel wallet should be more about function and less about form.
