Wearing lots of layers while traveling can help you stay both warm and cool whenever need be during an adventure abroad. Temperatures don't exactly stay consistent on an airplane, and some people wish they had an extra layer while others want less. By wearing a few different items of clothing, staying comfortable is guaranteed, which means you'll be able to pack fewer things in your suitcase since they'll be on your body.
If you fly often, then you know that airplanes are always super cold, while traveling itself can make you break a sweat.
