What's New, What's Hot is Travel Weekly's look at useful and fun travel gadgets, edited by Joe Rosen. First up, Fouta Harissa Textiles. Made from hand-loomed 100 percent cotton yarn from Italy and sporting Brazilian-inspired patterns, the foutas are woven by experienced artisans at Fouta Harissa's atelier in Tunisia, and then knotted, tasseled and fringed.

Vigilant travelers who want to protect their privacy in hotel rooms, guest houses, Airbnb bedrooms and bathrooms might be wise to investigate the potential of the Scout Hidden Camera Detector, which promises to detect cameras surreptitiously placed to catch you in unguarded and potential embarrassing moments.

A portable air purifier, the Wynd Essential is small enough to fit in your shoulder bag for travel but powerful enough to clear a hotel room of pollens, smoke, dust, dander, mold and germs.

National Geographic notes that you can do some good while enjoying the benefits of owning a handsome and practical tote bag that is branded by FEED, which was founded in 2007 by Lauren Bush to create products that help feed the world. Every FEED product is stamped with a number representing how many school meals are provided with its purchase.

If you are finding air travel literally a pain in the neck, this product might be for you. Promoted as ''adjustable, ergonomic and breathable,'' the Trtl Pillow Plus offers soft cushioned support for your head and neck and height adjustability to enable you to find the perfect sleep position in an imperfect setting, whether in a plane, train, motorcoach or car.
