NoSweat's patented design and Dri-LID technology is engineered to absorb forehead sweat and clear your line of vision. The game-changing technology permanently locks and seals all sweat inside the core, allowing the surface of the product to be completely dry, even when it is fully saturated.

NoSweat is worn by all NHL Officials and field tested by MiLB Umpires during the 2017 season and an officially licensed product of the PGA Tour.

Choose either a pack of 3 or 12 (best value - you save $2) liners.

I see the guys talking about the liners not sticking well. It is true you have to figure out the best way to use these. But once you do they are great!! I love them! No more sweat running down into my eyes. Also keeps the sweat stains off my hats.

So far so good since the season is over it's kind of hard to try this with my season caps but it works great with my off season caps. The sweat just does not go through to my cap. Love it.

Like the idea, but they just don't stick well enough for the cost.

Questions About This Product

Q: Are they disposable or can you continue to use them once they dry out?
– Jim Woodring

The liner is intended to be disposable and replaced once saturated with sweat. However, the average user finds that they can typically get 2-5 uses before it becomes fully saturated, depending on the amount one sweats.
