What's New What's Hot is Travel Weekly's look at useful and fun travel gadgets, edited by Joe Rosen. First up, the GoPro HD Hero2 Outdoor Edition Helmet Cam. Of course it has been done, but if you, too, want to make history by high-wire-walking across Niagara Falls, this is the camera to take with you to prove you did it. (If you trip and fall, the cam is waterproof to 197 feet.)

These don't-leave-home-without-'em kits will come in handy for leisure and biz travelers alike. The "for her" version, which comes in a pink pack, contains lip ointment, dental floss, a breath freshener, clear nail polish, nail polish remover pad, two clear hair elastics, hair spray, earring backs, stain remover towelette, double-sided tape, a latex-free bandage, deodorant towelettes, a sewing kit, a tampon and two Advil tablets.

These folding, lightweight aluminum walking sticks are at once practical and stylish. Designed for the Briggs Healthcare firm in the U.K., Switch Sticks can ease the stress of walking and standing in place and look good while doing so. Adjustable in one-inch increments, the walking sticks are fitted with a wrist strap in a coordinating color, have a painted maple wood handle or optional ergonomic handle and a water-resistant carry bag.

The TravelSmith Plane Case, which comes with four swivel wheels for the utmost in maneuverability, packs quite a load while still fitting underneath most airline seats. The ultrapractical carry-on offers three front top-zippered openings, two side pockets, a 40-inch telescoping handle and a detachable waterproof cosmetics holder. The bag, which comes in three solid colors and three quilted colors, also includes a mini tote free of charge.

For starters, you can't beat the price, as low as $10 on the Internet. Moreover, these lightweight, petite buds will fit very comfortably in your ears, a plus on those long plane rides. As for sound reproduction, the Wicked Little Buds are not designed to provide concert hall acoustics, but you can be sure that there is more audio quality built into these earphones than the standard equipment that comes with your smartphone or MP3 player.
