I used one in my bike helmet for a long tough terrane ride in hot, humid Houston, TX and it performed fantastically. Sweet running down everywhen but from where the pad was. It really made the ride much more enjoyable. Used another one when I played golf. Was thinking that it might interfere but I really could not even tell it was there. Again, it made the day much more enjoyable.
