Why hinder yourself with a big clunky suitcase when you can fit all your essentials into a reasonably sized sport or duffel bag? The practicality and versatility of these bags cannot be underestimated. Load these bags with your supplies for the beach; use them even when you're not traveling as a diaper or gym bag.
Most sport and 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. Get a bag with zippered compartments as they help with organization. Hidden pockets just under a bags flap are convenient for quickly accessing your passport and other essentials. Some sport or duffle bags come with a water resistant pocket on the side are great for storing wet clothes or shoes.
You may want to pick a bag with a mesh netting water bottle holder. Be sure to get a bag that is water resistant. There's nothing worse than getting your wardrobe wet during vacation. Get a bag that is tear resistant as well. Sport or Duffle bags are an advantage on road trips because they won't take up extra room in your car.
Sprawl out a bit in your vehicle—don't let oversized luggage prevent your comfort. Remember that lighter is better. While the sport or duffle bag may seem light in the store, wait until you get all your stuff in there. You can usually find a sport or duffle bag in any color you prefer so pick up the one that suits you. One other thing— be aware of overpriced bags—you should be able to find discount luggage that is the same quality as the higher priced stuff. Remember to duffle-up on your next trip.
