Traditionally, soldiers and people traveling in the great outdoors were the first people to discover the ease, comfort and practicality of traveling with a duffel bag. Those same folks may have actually been Belgian citizens of a sort since the duffel bag is named after a city in Belgian.
Little did these ancient travelers know that they were setting a trend that was soon to become one of the most popular of the 21st century. Travel bags such as sport or duffel bags are definitely your best bet when taking your shorter 2-4 day trip. They are also great for loading all your supplies for the beach; or use them even when you're not traveling a long distance, as a diaper or gym bag.
Most duffel bags have a comfortably padded strap that rests snugly on your shoulder. You'll notice the comfort and ease of your bag when you're standing in airport lines or carrying your bag through the hotel lobby. Most duffel bags are constructed with numerous zippered compartments that will help keep you organized. Hidden pockets just under a bag's flap are convenient for quickly accessing your passport and other essentials. Some sport or duffel bags come with a water resistant pocket on the side that is useful for storing wet clothes or shoes.
Many of the sporty utility bags are available with a mesh netting water bottle holder. Also, duffel bags that are made of quality material are strong and tear resistant. If traveling by car, they are an advantage because they take up so much less room. Sprawl out a bit - don't let oversized luggage ruin your comfort.
Remember that duffel bags are much lighter than standard luggage. They can easily be carried by older folks and young children. They are the most travel-wise choice for folks on the go.
