I purchased the sweat liners to use with the many ball caps I wear while working around the yard, to stop the sweat from running in my eyes and dripping on my glasses. The liners kept the sweat from my eyes and glasses, but I had a little sweat running down the side of my face, which was tolerable. The liners needed a minor adjustment periodically. Otherwise, they worked well and were comfortable.
