These sunglasses from Dragon were made for adventures, whether hiking climbing or skiing.
Considering the name, it's surprising to see no mention of cat 3 or 4 protection which is a particularly dark tint of lens suitable for open mountain ranges and high altitude trekking.
Having said that the lenses are clearly of a very high quality, with an injected polar film which helps prevent surface glare and hydrophobic and oleophobic coatings, which sound very grand and technical but simply put means they shed water and don't get grubby too easily.
The leather side shields are vital if you're mountaineering in high alpine environments, on the Mountaineerx they attach with refreshing simplicity with a couple of clips and a loop over the arms. They provide all round protection from the sun's rays, they also hamper visibility but this is to be expected.
The removeable rope lanyard system is easily adjustable to suit your head size and keeps the sunglasses secure which is great for hiking over challenging terrain.
The ace up the sleeve of the Mountaineerx becomes apparent when you remove both the lanyard and side shields revealing a seriously stylish pair of sunglasses that are great for everyday wear.
Overall, we loved the Mountaineerx sunglasses for their performance and great looks both on and off the mountain and their versatility perhaps justifies the high price tag.
