What's New, What's Hot is Travel Weekly's look at useful and fun travel gadgets, edited by Joe Rosen. First up is NapAnywhere, the latest thing in travel pillows -- small enough to fit flat in a briefcase or laptop carry-on and designed to provide effective head support when you are seated, for example, in an airplane. This contraption could be the difference between sleeping through a long-distance flight or arriving, instead, sleepless and with a stiff neck.

More a don't-travel product than a travel product as such, the Breathometer gives you the ability to be a DUI preventer both for yourself and your friends after a night on the town. Designed to function as a breathalyzer when used in conjunction with an app downloaded to a smartphone or tablet, the Breathometer, which is small enough to fit on a key ring, simply plugs directly into the audio jack of your device. The Breathometer, which is registered with the FDA, has a detection range from 0.00 BAC (blood alcohol content) to 0.20.

Some travelers prefer to carry their essentials in a backpack, wherever and whenever they go, and for them an all-purpose carrier such as the Ogio Newt 15 should suit them perfectly. The backpack has a padded back panel for comfort; dual, adjustable foam shoulder straps and sternum strap for stability; an easy-access mesh pocket; a zippered stash pocket on the back panel; a zippered, fleece-lined valuables pocket; a padded tablet sleeve in the main compartment; and a fleece-lined, protective pocket for electronics.

Made from durable, high-grade aluminum, Switch Sticks are a traveler's delight in that they can be folded down into four sections and easily strapped together with an enclosed Velcro strap. When the strap is released, the sections snap back into place without the need of screwing them together. Each walking stick, which weighs only 13.5 ounces and is adjustable in 12-inch increments from 32 to 37 inches, comes with a coordinating wrist strap, ferrule, the Velcro band and carry bag.

Sized to fit any standard airline overhead luggage bin, the Skooba Laptop Weekender V.3 carry-on can handle a two-days'-worth wardrobe as well as a 15-inch laptop. The bag features a padded laptop compartment protected by bumpers on the sides and bottom to provide shock absorption. Moreover, the laptop can be easily accessed and removed for TSA inspection without having to open the main compartment. In addition, it has more than 12 pockets, compartments and organizers, including fully padded pockets for tablets and other electronics.
