Travelers often ask the question, "What do I wear?" -- especially if they're jet-setting from a cold country to a hot one.

According to one travel website, they should wear the new Winter Sun Travel Outfit.

The outfit, created by the site TravelSupermarket, is designed to "take you from Gatwick to Grenada in one garment," according to The Daily Mail. It has versions for both women and children, made from "heat-retentive and breathable" materials."

'[They] are an easy answer to ensuring mums and kids no longer need to fear arriving in their holiday resort feeling tired, flustered and overheated,' the website said, according to The Daily Mail.

The idea came about in response to TravelSupermarket's research indicating that 57 percent of British vacationers had been caught off guard by the weather in their travel destination, The Daily Mail reported. One in 10 of those surveyed said they changed their outfit in the plane's bathroom, while almost a third admitted they remained in their winter clothes, sweating, until they could change in their hotel rooms.

This outfit is something of a solution.

The women's garment has one winter and two summer styles - the cold weather one is an all-in-one long-sleeved hooded dress with a pair of mittens attached, including an in-built inflatable neck pillow and pockets, The Daily Mail reported.

For the warm weather, the outfit can be stripped down into a mini-skirt, and the upper jacket can be turned into a beach bag, according to The Daily Mail.

The children's outfit is a lime-green, frog-styled onesie. The padded hood makes it comfortable for kids to take a nap if they choose, and poppers allow for easy diaper changing. The outfit also includes blackboard kneepads, so kids could doodle on them to pass the time, The Daily Mail reported.

Parents can also rest easy, because with this outfit, they can check their kids' whereabouts, according to The Daily Mail -- it contains an inbuilt GPS tracker that synchronizes to a cell phone SIM chip.
