I was thinking the same thing before I ready the article; what does this dude do borrow equipment from everyone he meets?! I carry more rock climbing gear on a multi-pitch climb than stuff he owns!

But then I read the description and it sounds like it's for general working out or something? IDK, I've never personally needed chalk for or met anyone that needed chalk for lifting. Perhaps he works out in very humid climates, but I'd think there would be chalk provided at the gyms? Likely an item that could be practically dropped?
