Our designers have developed this chalk bag for climbers who enjoy indoor climbing and big wall climbing, whatever their level.
WHY ADD A FILTER?
A study by the Technical University of Darmstadt shows that the climbing has a high concentration of PM 10 due to chalk in the air.
In parallel, we've noticed that chalk bags can be accidentally knocked over on the floor, at the base of boulders/climbing routes.
When this happens, climbers are wasting their chalk and adding to the concentration of PM 10 in the air.
This is why, to reduce this chalk loss, our engineers have designed a textile filter, built into the chalk bag.
DOESN'T THE FILTER MAKE IT HARDER TO GET YOUR HAND IN TO CHALK UP?
That was the challenge we faced!
After numerous prototypes and tests, here is the winning formula:
➡highly elasticated and smooth fabric so as not to snag the hand as it enters the bag;
➡a slit across the middle to let the hand in easily;
Of course, it will always be slightly easier to get your hand into a chalk bag without a filter, but after several field tests with climbers, the problem has been solved!
HOW WAS THIS 55% DIFFERENCE MEASURED?
