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 $9.97) liners.

Works great, love this. Left no residue on regular hats, but be careful on skull caps. There will be residue left.

Terrific product for those us of that work a lot of baseball games in the summer heat or early season football in August and September. As an added bonus, I believe it helps keep my hats cleaner with fewer sweat stains. Two thumbs up!!

As someone who sweats a lot this has been a hat saver and made those hot days much better at keeping sweat down. It does make the cap slightly tighter but with the FlexFit hat it's not really noticeable and with the fitted cap, I didn't notice either. Next summer I will definitely be adding a few more of these to my bag and caps.

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.
