1. RainScarf ($25)
Keep warm and cozy at 30,000 feet with this reversible scarf, which can also free you of the need for a raincoat and umbrella. One side is water-resistant, with a tuckaway hood and a few concealed compartments for valuables. Buy it at Amazon.
2. Sockwell Elevation Firm Compression Socks ($25)
Compression socks improve circulation, preventing swelling, fatigue, and worse: blood clots. Sockwell's durable, "downright stylish" offering won't bunch at the knee and comes in several patterns and solid colors. Buy it at Amazon.
3. BetterBack ($59)
Airline seats can be tough on the back, but there are products that can help. This clever packable is among the most portable. It's a back pad held in place by straps that go over your knees, providing a "surprisingly comfortable" way to achieve a healthy sitting posture. Buy it at Amazon.
4. Kiehl's Hydrating Mist ($27)
A favorite carry-on among fashion models, this refreshing facial mist hydrates the skin with a combination of Tibetan ginseng, cactus flower, and the essential oils of lavender, geranium, and rosemary. It can be used to set makeup as well as throughout the day. Buy it at Amazon.
5. Sennheiser HD1 Wireless Headphones ($400)
Though Bose headphones are better for noise canceling, these offer a step up in audio quality and build. The leather cups are "mind-blowingly" soft. The sound? Impressive — "crisp on the high end," with "just enough bass to lend a nice punch." Buy it at Amazon.
