This is a Sewn Terry Cloth - Replacement Sizing Liner - for the Lifer Helmet. With the terry cloth sewn onto the liner it is more durable and will not break down as fast as the standard Lifer sizing liners.
The terry cloth also helps absorb sweat. The Sizing is a little different for the Terry liner so we recommend that you order a Sewn Terry liner one size smaller than your normal size.
Sizing Help: Choose a size down example: if you usually have Large liners in your helmet you want to choose a Medium Sewn Terry liner.
