Petzl’s Power Crunch chalk is to be had in three sizes (25 g, 100 g, and 200 g), convenient for each climber. The small 25 g size is the easiest amount for a day on the crag or a session on the gym. The 100 g will fill a chalk bag more than one times and the 200 g is ideal for those with chalk hungry hands who never appear to have enough chalk to get through a tough summer day of mountain climbing.
A mixture of chalk chunks and powder that helps reduce dust
Easy opening bags
The Power Crunch has a re-sealable closure and will rise up by itself making it easier to fill a chalkbag
