You may think of a bag as being primarily a woman's accessory. But today, there are many types of bags that are very cool and masculine. Plus, with all the gadgets that we carry today, from digital cameras to iPads to laptops, a bag is just downright practical. Here are some bag styles that work well for men.

Briefcases - The briefcase is the most classic men's bag. I'll bet you remember your father carrying a briefcase to work when you were a child, (I know I do). Early briefcase designs looked like rectangular boxes with sharp edges. But today, modern designs have softened a bit. You can find briefcases in a variety of finishes. Look for a genuine leather briefcase in a shade of brown, reddish-brown or black. You can also look for stylish touches like exterior buckles, such as the Toscanella Triple Gusset Men's Briefcase by Pierotucci. Although briefcases are quite versatile, I would not recommend bringing one to a job interview. Instead, opt for a slim messenger bag or small portfolio in this case.

Newsboy bag - A newsboy bag is a great accessory for a casual outfit. The style is, of course, modeled after the canvas bags that newsboys would sling their newspapers in while peddling the papers on a street corner. So because of its inherent design, a newsboy bag is good for carrying a small stash of items around town. For example, if you're taking the train from Baltimore to DC to do some sight-seeing for the day, a newsboy bag is just the right size to bring essentials such as your keys, wallet, camera and phone, along with a water bottle and some snacks. For the most versatility, look for a bag with a shoulder strap that fits all the way across the front of your chest. This way, you can have both of your hands free. I like the American Eagle Newsboy Bag, since it has a casual but polished appearance and its neutral colors would go well with any outfit.

Holdall Bag - The holdall bag is perfect for weekend getaway ventures, overnight business trips, and other short travels. Because the holdall bag comes in many different styles and shapes, take the time to find one that best suits your needs. One of my favorite styles is the Valise Carry On by Bric's Life Collection. This bag is completely practical while still stylish. It is made of genuine leather and contains a waterproof lining. Additionally, it has an adjustable shoulder strap and can be padlocked. The best part? It has a roomy interior but is still small enough to be brought on a plane as a carry on. While most holdall bags have one large inner zippered compartment, you can also look for one with a smaller inner pocket in order to hold little items such as toiletries, tie accessories, or your iPod.

Tote Bag - Not to be confused with its less masculine cousins the diaper bag and the beach bag, the men's tote bag is an updated look on the briefcase. It's a bit sportier than luggage, and a good modern, versatile bag. Coach makes some excellent men's tote bags, while the Filson Rucksack is a good style if you would like a sporty looking tote that can convert into a backpack. The best tote bags are both fashionable and functional. If you are, in fact, on the prowl for a Dad Bag that doesn't look girly, check out the websites Dad Gear and Diaper Dude. They have men's tote bags that are specifically designed to carry bottles, diapers and other kid essentials.
