The plastic suit makes you sweat. That's about all it does well.

It crinkles every time you squat. After a couple of weeks it smells like a shower curtain.

This hoodie has a smooth gray layer inside that keeps your body heat in. There's no plastic in it.

1 More sweat from the same workout

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
Left: a gray tee after a regular hoodie. Right: the same workout in this one.

Keep your usual workout. Same treadmill, same 20 minutes.

The heat stays in, so most people sweat more than in a regular top. You can see it on your tee after.

These reviews are for our Pro Sauna Sleeveless Hoodie, word for word. This hoodie is the long-sleeve version.

"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

It's lined, so it keeps your body heat in. You get warm fast, even on a cold morning.

The long sleeves and the hood keep your arms and head warm too. The sleeves stay put when you lift.

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

3 Nobody at the gym stares at you

It's plain black on the outside, with a hood and a front pocket. The warm layer is on the inside where nobody sees it.

No crinkle when you squat. The guy next to you sees a hoodie and gets back to his set.

It's light, and it isn't stiff or bulky. You can run and lift in it like any other hoodie.

"It also doesn't feel heavy or damp like if I was wearing a regular sweater."

5 It fits like the hoodie you already own
