Review of White & Black Sweat Liners — Patented SweatLock™Start with the type of headwear you’ll use: hat, trucker hat, visor or helmet. For smaller headwear, select Youth and choose a youth hat or youth helmet liner. The product photo updates so you can see the selected liner.
NoSweat recommends replacing a liner after around three daily wears on average. Sweat, weather and activity affect how long it lasts. Replace it sooner when needed; each liner is disposable.
NoSweat advises against cutting the liners because this releases the SweatLock™ beads inside. Choose the liner made for your type of headwear.
No. The adhesive side attaches to the inside of your headwear. The soft, absorbent side faces your forehead. Press firmly when applying the liner.
Choose the color you prefer for your headwear. Combo packs contain half white and half black liners. Available colors and pack sizes depend on the liner style you choose.
No. You’re buying NoSweat liners. Headwear shown in the photos demonstrates where the liners fit.
