Petzl LINER Cap

The Petzl LINER is a lightweight cap designed to be worn under a helmet. It is aimed at climbers, via ferrata users and anyone needing a thin, close-fitting layer to wick sweat without adding bulk under a helmet.

Main features

• Breathable fabric wicks sweat and dries quickly
• Seamless, fitted cut for comfort under a helmet
• Very low weight — almost unnoticeable under headgear
• Machine washable (water temperature below 40 °C)
• Available in two sizes to fit different head circumferences

Designed for use under climbing or cycling helmets and during high-intensity activities when moisture control and protection from chafing are needed. Suitable for warmer conditions in spring and summer or for layered use during active mountain outings.
