The same man in the same locker room after two sessions: on the left he sits on the bench in a gray tee with a normal sweat mark at the collar, a regular gray hoodie over his shoulder, on the right he stands holding the black Pro Sauna Hoodie, gray lining showing, with a much bigger sweat patch down the chest of his tee

No new routine and no plastic suit. It's a black hoodie with a warm gray lining inside.

You get hot faster, so most guys sweat more doing the same workout.

Here are 5 reasons guys keep one in the gym bag.

1 A soaked tee after the same workout

Do your normal workout with it on. Most people sweat more in it than in a regular top. Then lift it up and look at your tee.

"In 20 minutes on the treadmill I am sweating more than 45 minutes with a normal t shirt. Awesome!"

2 You warm up fast, even in a cold garage

The lining keeps your body heat in. So you warm up fast and start sweating sooner.

On a cold morning, keep the hood up while you warm up.

"I train with it in the gym, in the garage and outdoors. The fit is comfortable and you get an incredible sweat."

3 It's light and easy to move in

No plastic and no bulk. It moves like a normal hoodie when you lift or run.

"It also doesn't feel heavy or damp like if I was wearing a regular sweater."
Vue X., review of the Pro Sauna Sleeveless Hoodie

It fits true to size, S to 4XL. Get the size you wear in a normal hoodie.

Other guys at the gym just see a black hoodie. The warm lining is on the inside, where no one sees it.
