What's New, What's Hot is Travel Weekly's look at useful and fun travel gadgets, edited by Joe Rosen. First up, Feetures Socks' Lifestyle Collection. The socks, which are styled as hidden or crew, offer targeted compression, which lifts and supports the arch, and as such should help ease the stress on a traveler's typically aching feet.

For the RV camper, soft adventurer or vacationer going mobile, the Mr. Steak 1-Burner Portable Grill is designed to go where you go (within reason). Despite being relatively compact, the 1-Burner's ceramic infrared burners fire up to 1,000 degrees F (14,000 BTUs) and have 165 square inches of cooking space. It is designed to be used with a 1-pound propane cylinder.

Despite weighing only 2.3 pounds, the Tortuga Homebase Backpack -- it works as a carryon as well -- sports isolation sleeves for a laptop (padded) and tablet and provides ample room for the other gear and garments you might need for a weekend on the road. Constructed of waterproof sailcloth with stowable foam shoulder straps for comfort, it measures 20.75 by 12.3 by 8.25 and comes with a handy detachable packing cube.

Dune Jewelry features jewelry and accessories handcrafted from sand and natural elements sourced from thousands of locations worldwide. Made in the U.S., the line creates tangible mementos of vacations, hometowns, iconic locations and destinations such as resorts, ballparks, beaches and golf courses, virtually anywhere you have been.

Apart from its size, the Doctor Plotka's Travel Toothbrush has other attributes, such as a ''silver bristle technology'' that eliminates 99.9 percent of bacteria build-up on bristles, flossing bristles and ''superior'' cleaning bristles. And one thing for certain: It packs light.
