We've all been there... Lowering from a windy route, jumping off a gym boulder, setting our chalk bag aside between burns—only to look down and watch, in slow motion, our bag tip and spill 5 ounces of precious Unicorn Dust into the dirt, gym floor, or thin air.

What if there was a way to seal a chalk bag in a way that reduces chalk dust emissions and prevents unwanted spills without even touching it? 

As it turns out, there is! After a bit of rigorous testing with the FrictionLabs athlete team, we are psyched to announce an exclusive partnership with YY Vertical and introduce the revolutionary Chalk Stopper to climbers in the USA and Canada!
