A throwback to old-school alpine style, but it's built with 21st century technology

PERFORMANCE
Protective side shields
Inspired by classic alpine design, Heron Glacier feature leather side shields and a detachable centerpiece to block out sunlight and protect against glare, dust, and wind.

OPTICS
Ultraclear Cat. 4 lenses
The brown tint is optimal for snow as the warm perception enhances contrasts, while anti-fog coating prevents condensation during long ascents. The ultraclear Cat. 4 lenses have a 6% VLT which reduces eyestrain and provide all-day comfort. The lenses have been cut from 2 mm polycarbonate and are shatterproof for maximized safety.

MATERIALS
Adjustable temples
The frame is made from Swiss-invented TR90® polyamide and is incredibly lightweight yet durable. Our fully adjustable and unique temples can be shaped around your ears entirely to your liking, allowing maximum comfort for long days in high alpine territory.

PACKAGING
Protective case
Heron Glacier comes protected in a stylish faux leather protective case along with a cleaning cloth. They are delivered plastic free in our VALLON box.
