Some bulkier items of clothing, such as puffer coats, can do double duty during travel.
Ski.com's packing list recommends "comfortable, waterproof boots or shoes with good tread — especially if it's snowing in the town or base village or if you want to enjoy outdoor winter activities like snowshoeing, snow tubing or dog sledding."
"Pack a wrap!" Klopp added. "A beautiful cashmere wrap can warm your head, your shoulders, your neck and everything else that needs a little cozy warmth."
Hand and feet warmers, snacks and energy bars, sun glasses and sunscreen are also a good idea.
"Packing cubes are a great investment. They help keep everything snug and tightly compact in a carry-on or suitcase," Loffredi said.
And don't forget to take advantage of rentals for large equipment.
"You can rent helmets, too, along with the rest of your ski or snowboard equipment," notes Ski.com.
If you must pack your own equipment, be sure it's adequately protected.
"Consider additional travel insurance to protect your ski or winter sports equipment," Loffredi said.
