A hip flask is one of the mainstays of a gentleman's accessory collection. Being able to casually and elegantly sip a bit of your favorite drink in any situation is an old world pleasure that can still be had today. In addition, a hip flask makes for a personal and inexpensive gift, so follow these steps to buy a hip flask for yourself or someone you know.
Decide on size. Hip flasks come in a variety of sizes, with a few that are fairly standard. Choose among the 2.5-ounce, 4-ounce and 8-ounce versions of the flask. Smaller flasks increase the discreetness of the flask while larger versions allow for that extra shot. So, think about the needs of the drinker to decide on the correct size.

Set your budget. Hip flasks start around a few dollars for a very simple, brass tacks version and can range up to the many thousands of dollars for gold, platinum or historically valuable items. Think about how much you want to spend so you know where to look and what to look for.
