FOUR® Thermal Skull Cap

Black

Built for colder conditions. Designed for a daily wear.

The FOUR® Thermal Skull Cap is a cold-weather performance layer engineered to retain heat while maintaining breathability and mobility. Crafted from a dense waffle-knit thermal fabric, it delivers insulation without bulk — making it ideal for outdoor training, late nights, early mornings, and winter movement.

This piece is designed to lock in warmth, sit comfortably under jackets and helmets, and hold its structure through wear.

A true utility uniform essential.
