Which Helmets Can I Use the Thermal Liner With?

The HA18 Helmet Liner is a versatile liner that isn't designed for any particular hard hat. Therefore we would recommend that you use the liner with any of our Hard Hats range.

How Warm Is the Portwest HA18 Liner Cap?

The Liner Cap is an excellent thermal liner, that is recommended for freezing cold outdoor work, sub zero work and freezer or cold store work. It is only recommended for these tasks because it is incredibly warm, offering superb insulation against freezing temperatures thanks to its polyester and elastane lining.

How Comfortable Is the Portwest Thermal Helmet Liner Cap?
