The African Safari-goer (by Steve Boyes, National Geographic Expeditions Africa expert)

• Good chemistry: New insect-repellent fabrics last for 70 washes but can be uncomfortable; opt for whatever makes you most comfortable.
• How low can you go: Power at safari camps is spotty. Carry a flashlight and low-light binoculars.
• Do: Bring a hat (wide-brimmed for walking/boating, baseball cap for game drives).
• Don’t: Wear whites or brights, which can both attract and scare wildlife.

The Urban Culture Vulture (by Tim Jepson, National Geographic Traveler Italy guidebook author)

• Does not compute: Bulky in the city is not a good look — leave the laptop at home.
• Clothes call: Pack a lightweight rain pullover that can slip into a pocket or purse.
• Do: Bring a pair of foam earplugs. Towns and cities can be noisy at night, from church bells and motorbikes to carousers.
• Don’t: Carry a conspicuous foldout map. Instead, make photocopies of detailed street maps.

The Rocky Mountain Hiker (by Boyd Matson, National Geographic Weekend radio host)

• Think in Threes: Pile on a base layer (form-fitting, fast-drying), warming layer (sweater, fleece), and light shell (wind/rain jacket).
• Stick in the mud: A collapsible hiking pole buoys stamina.
• Do: Bring convertible zip-off pants.
• Don’t: Wear denim.
