There have been some incredible inventions in the world, including big ones like electricity, computers and telephones as well as a variety of inventions made within the fashion industry.

Fashion designers are inventors too since they create masterpieces through fabrics that transcend generations since many styles and designs tend to return years later from when they originated.

So what do inventions have to do with 5 Seconds of Summer? Well, the band's bassist declared what he thinks the "best invention ever" is on Twitter Monday.

It is definitely not electricity even though it would seem plausible for him to go in that direction since he plays a bass guitar.

Anyway, Calum Hood snapped a photo of his fabric-covered arm and hand, which is telling of the invention he thinks is so rad.

There are shirts that are long-sleeved that have thumbholes. He loves the thumbholes.

"I'm calling best invention ever," he dished while showing off his long-sleeved top with the thumbhole on display.

These shirts are perfect for keeping hands warm! We bet if Hood happens to experience extremely cold hands these shirts are definitely perfect for him since he still has the ability to play his bass while staying warm. Otherwise we imagine if he had on a regular long-sleeved shirt and wanted his hands covered he would run into a bit of a pickle especially if he were expected to play his bass.
