Testing shows transmitted impact loads were reduced 25-35% in a helmet equipped with ZetaLiner® Helmet Liner and SoftSeal/HushKit® Combo ear seals and insulation kit, compared to the original helmet. Visco-elastic foam sewn into cool, washable wear-resistant fabric. Eliminates top-of-head hot spots. Self-wicking fabric controls heat buildup by evaporative cooling of perspiration. Eliminates "bob and roll" when mounting external equipment. Lighter weight than other liners. Fitting only takes a few minutes. Testing shows ZetaLiner® helmet Liner reduces skin temperature 1.5°F compared to existing liner systems. The ZetaLiner® Helmet Liner comes in four thicknesses: 1/4", 3/8", 1/2" and 5/8". The most commonly used thickness is 3/8". To select the proper ZetaLiner® Helmet Liner thickness, review the information below, then select your size and thickness. NOTE: If your TPL®* has been heated and fitted, you will probably need a ZetaLiner® Helmet Liner one thickness thinner than those listed below.

IF YOUR TPL® LINER HAS: THEN TRY:
2 Layers 1/4" ZetaLiner® Liner
3 Layers 3/8" ZetaLiner® Liner
4-5 Layers 1/2" ZetaLiner® Liner
5+ Layers 5/8" ZetaLiner® Liner
