Climbing nuts tested to destruction in real rock. Watch us do our first tests of passive climbing protection in some bomber granite. We tested a Black Diamond Micro Stopper, some BD stoppers and an older Wild country nut. Let us know if you want to see more tests of passive climbing protection.

Breaking Gear Fear

Edutainment has been a great way to help people understand their gear, and know the true limitations of it.  Watching HOW gear fails is more important than the force itself, as almost all gear is super good enough.  It's more important to share information on how to stay safe than it is to have a paywall.  We hope our stoke is contagious.
