Black Diamond

Black Diamond have been making top end gear for climbing and skiing since 1957 by taking their experiences on rock, ice, and snow to make some of the best gear for climbers and skiers all over the world.

They offer a complete range of skiing, touring, climbing, mountaineering, bouldering and via ferrata products including Gloves, Boots, Boots, Safety and Protection, Ice Axes, Crampons that have set standards in numerous areas. Black Diamond is a company of explores that are constantly trying to create new and better ways of doing what they love and giving back to skiers, mountaineers, and climbers that want to get out and have fun on the mountains.    

Sizing systems can vary between brands.  While US to UK size conversion can be fairly straightforward, UK to European size conversion is often rounded to the nearest half-size which is where confusion can arise.  Throw Japanese linear measure and Mondopoint into the mix and it can be quite the challenge to convert from one measurement accurately to another.

As an online company, we value the importance of providing you with the most up to date fit and sizing information to ensure you find the perfect fit the first time.  As such, all our size conversion charts are checked regularly and updated based on manufacturer's guidelines and recommendations.

Think we're missing key info?  Let us know and we'll take care of it.
