Helmet Black Diamond Vapor

Black Diamond Vapor is a lightweight helmet for both indoor and outdoor climbing.
The compact, half-dome, low-profile, open-top helmet delivers unmatched airflow and an iconic silhouette.
The two-piece construction provides added protection and reduced weight.
The construction features a layer of ultra-lightweight ALUULA composite under a polycarbonate shell for added protection and reduced weight.
A layer of Kevlar and carbon fiber is sandwiched between the inner shell and the shell.
The sides are made of molded EPP foam, which provides ample ventilation and a sleek look.
The ultra-lightweight attachment system uses a specially designed cord to minimize weight.
Streamlined (and interchangeable) headlamp mounts are ready for use after dark.
Black Diamond Vapor is available in 5 colors (black, white, red, dark green, gray) and 2 sizes (S/M, M/L).

MANUFACTURER

Black Diamond
Black Diamond is a world-famous manufacturer of equipment for mountaineering, skiing and mountain sports, based in Utah, USA, and also has an office in Innsbruck, Austria. Black Diamond is owned by Clarus Corporation, which also owns Pieps and Sierra Bullets.
The history of Black Diamond goes back to 1957 - a young climber and surfer Yvon Chouinard buys a used blacksmith's horn, a 138-pound anvil and a hammer. In his improvised forge, he begins to manually forge rock hooks, which he later sells directly from the trunk of his car, providing himself with a livelihood.
Now Black Diamond Equipment is a huge company with a turnover of 200 million dollars a year, headquartered on three continents (USA, Switzerland and China), including several reputable brands (Bibler Tent, Pieps, POC, Gregory), which are still headed by young enthusiasts of their business, continuing to raise the bar of comfort and safety while relaxing in the mountains.
Black Diamond is a great example of a socially responsible business - the company sponsors many non-profit organizations that somehow support mountain sports - American Alpine Club, The Access Fund, etc.
