Petzl BEANIE Helmet Liner

The BEANIE is a low‑profile insulating beanie designed to be worn under a helmet. It is intended for climbers, ski mountaineers and technical users who need a thin, warm and breathable layer beneath a helmet.

Key benefits

• Seamless, shaped fit provides comfortable wear under a helmet without pressure points.
• PrimaLoft® insulation offers thermal protection even in damp conditions.
• Breathable fabric wicks moisture and dries quickly, reducing sweating inside the helmet.
• Lower section includes a wind‑resistant layer (Windstopper® in some market descriptions) to protect from chill and drafts.
• Reversible, close fit allows easy adjustment and multiple wearing options.

The BEANIE is suited to technical climbing, via ferrata, winter ascents and ski‑touring in cold or windy conditions where a thin insulated layer under the helmet is required. Machine washable at 30 °C.
