Vallon and Nimsdai launching the Heron Glacier Nimsdai Edition

The Vallon Heron Glacier Nimsdai Edition sunglasses are designed for mountaineering and are perfect for climbing the world’s tallest peaks. These sunglasses have anti-reflective Category 4 lenses that are crucial for high-altitude adventures. Category 4 glasses provide the highest level of protection in sunglasses and are ideal for extreme conditions, especially when there is intense sunlight and glare, like on big mountains.

With a nod to the classic style of alpine design the Vallon Heron Glacier Nimsdai Edition, has leather side shields and a detachable centrepiece to block out sunlight and protect against glare, dust, and wind. It comes in two exclusive new colourways: Matte Black and Glacier White – which is Nimsdai’s favourite.

Tested by Nimsdai

Nimsdai has tested the new glasses on the Big Mountains including Everest, Lhotse, Annapurna and Makalu. He said: “At high altitude you need eye protection that will protect you and won’t let you down. The Heron Glacier Nimsdai Edition is tough, provides the ultimate eye protection with a Cat 4 rating – and it looks boss too. Everything you need for high-altitude adventure.”

Designed for adventure, the ultra-clear lenses are cut from 2mm thick polycarbonate and are shatterproof for added safety. The warm brown tint blocks blue light and enhances contrasts and depth perception, which is advantageous on snow and ice. The lenses contain an anti-fog coating on the inside to prevent condensation. The central leather piece can be removed for added ventilation.

Lightweight and durable

The frame is made from Swiss-invented TR90 polyamide, which is not only very durable, it is incredibly lightweight at only 25 grams. The 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.

Vallon said: “This is a Nimsdai twist on our classic Heron design. Functional, stylish and approved by the best in the world – the Heron Glacier Nimsdai Edition is the ultimate highaltitude eyewear.”

The new exclusive Nimsdai Heron Glacier costs € 129 and is only available in the Vallon webshop.
