Gentlemen, this might get your knickers in a twist, but a line of men's underwear is apparently hitting all the right spots.

A male version of the female "one piece" has been so popular online the brand behind it is working on a swimwear version, reports news.com.au.

The form-fitted, body-hugging undergarment, known as the "Finwick", has been described as a "multifunctional, masculine body suit" which "follows the shape of the male body".

Rufskin, the San Diego-based brand behind the pure white design, say the underwear "can be used as an undergarment as well as a top with the advantage of staying in place under one's pants or shorts".

It's "ideal for support during any work out or just looking sharp at any time".

The material, a nylon microfibre, is said to come with a "superior stretch" and "ultra soft hand".

And apparently, the guys are lapping it up.

Douglas Coats, President of menswear brand Rufskin, told news.com.au the brand has "done well with one piece underwear styles now for quite some time".

"In the same concept we are in production with a swim version of this particular garment," he told news.com.au.

And if you were worried about those cold days downstairs, gents, the underwear is double layered with a "contoured" pouch.

"Words don't do this collection justice. You won't believe until you touch."

The piece sells for a recommended retail price of $103.
