What causes head sweat?

This video features Carpe's Chief Medical Advisor, Dr. Ashish Bhatia, speaking about head and face sweat.

This thing works great. Used it for the first time last week playing golf. It was 90° and not a drop of sweat went to my new hat. I went and bought three more. Great product.

It reduces the amount of sweat dripping into my eyes when out performing chores in warm weather.

I solely ordered this to product to protect the inside of my hats from makeup and minor sweating. I do plan to order replacements as time goes on so overall I’m pleased with the product.

The most frustrating thing about playing tennis with sweaty hands is the racket spinning. . .Carpe gives me a reliable grip.


My dermatologist recommended Carpe - and it worked! It's the only thing that actually worked. 


I have one less thing to worry about when it comes to taking tests! No more sweaty hands! 


The most effective antiperspirant I've ever used. I love it!

OMG I love the hat liners. They do what they say they're going to do and I'm so happy. The only thing I'd like to say is females hats/caps a a little smaller then males so I had to adjust mine just a little. Love them!!!
