Seirus Thermax Skull Liner

We like the Skull Liner for its minimalist design that performs. It keeps sweat off your skin, traps just enough heat, and feels comfortable even during long sessions.

Why we like it:

Snug, stretch fit designed to wear under helmets, hats, or on its own.

Features and Functions:

A go-to layer for anyone who needs low-profile warmth that performs in motion.

Fit and Sizing:

Made with ultra-thin Thermax® fabric for wicking warmth and flat seam construction for comfort. The 3-in-1 design works under helmets, layers easily under hats, or can be worn alone.

Bottom Line:

Lightweight, 3-in-1 Thermax® skull liner for wicking warmth under helmets or hats.
