The Organic Lunch Bag Chalk Bucket aims to kill two birds with one stone. First it stores and transports your chalk with a similar closure system to a "dry bag" that is more securely closed than just a normal chalk bag with its often leaky drawstring closures. Once at the rocks the Lunch Bag opens up and turns into a bouldering bucket or easily accessible re-chalking station for smaller bags at the crags. It's an innovative approach and one that might appeal to climbers who want an all-in-one solution.
The Metolius Powderhorn has the similar "dry bag" style, roll up closure system but does not function as a chalk bag/bouldering bucket very well. Although the Organic is better than the Metolius because it doubles as a bouldering bucket and also holds more chalk, the Lunch Bag still leaks chalk out of the closure system about the same as the Metolius from time to time if it's not securely rolled up or if it is filled too full to close all the way.
