Seasoned travel veterans keep a bag packed for impromptu trips. Traveling with kids takes a bit more forethought, but having a pre-packed travel kit can make life easier for everyone. While each vacation has its own check list (swim suits and pool toys, hiking boots and zip-off pants....) there are a few essentials that make travel easier for everyone—especially families with children.

ExOfficio Buzz-Off Clothing
Most parents don't enjoy coating their kids in insect repellent, especially just for the quick roadside stops that are inevitably followed by hours in a stuffy car. The Buzz Off line of children's clothes repels mosquitoes, ticks, chiggers, black flies, and no-see-ums, and protects vulnerable skin with UPF 30+ protection. The Buzz Off Kids Skeeter Capris are a 70 percent cotton, 30percent nylon blend, with a comfortable drawstring waist.

Columbia Sweaters and Jackets
The 100 percent polyester fleece Steens Mountain Sweater (boys) and Benton Springs Sweater (girls) are ideal for everything from camping to sightseeing, with a water-resistant coating and moisture-shedding fabric. For summer squalls, pair them with a lightweight, packable rain shell. The Granite Tors Jacket is waterproof and breathable, with articulated elbows and a moisture wicking mesh lining.
