The Salewa Ortles 2 WINDSTOPPER® Beanie in Black Out is a slim windproof hat built on a GORE-TEX® INFINIUM® WINDSTOPPER® laminate, cut to be worn under a climbing or ski helmet. At 30 g it is the thinnest of Salewa's beanies, and its warmth comes from blocking wind rather than from bulk.

• Windproof membrane: the WINDSTOPPER® laminate at the forehead and ears is what makes a thin hat feel warm on an exposed ridge.
• Helmet compatible: the slim fit is sized to go under a mountaineering or ski helmet without pressure.
• Flatlock seams: no raised seams to press into the scalp under a helmet shell.
• Polarlite stretch panels: the stretch inserts let the hat move and breathe where the membrane does not need to be.
• Three sizes: S, M and L rather than one size, which matters for a hat worn under a helmet.
• 30 g with a reflective logo: the lightest beanie in the Salewa range.
• Polarlite® stretch panels
