My simple knitted chalk bag has been serving me well at the bouldering gym so far, and has even gotten some compliments from other climbers. I’ve gotten another friend to start climbing with us, and instead of carrying around her chalk in the plastic baggie it came in, I made her a bag of her own:
The black and blue color scheme might be more appropriate for my bag, as every climbing session I bang my knees or legs into something: a hold, the wall, the floor, etc. My knees are so often bruised it has become a running joke with the friends I climb with.
Instead of making an I-cord drawstring like I did before, I used a round shoelace and a drawstring cord lock, which is so much easier to use. The I-cord is too thick to really feed through a cord lock, so I just tie it closed. It doesn’t close as tightly, though, so everything in my bag gets a decent dusting of chalk.
