How to pack MagSafe cable to prevent its breaking?

I am looking for a (most) powercord-safe way to pack my MagSafe adapter for a daily backpack commute. Official Apple recommendations (as illustrated by third-party videos like this ) don't prevent the breaks at all, as my experience with 2 MagSafes showed. Third-party supplements promising a solution don't sound very convincing: - MagSavior is clearly a hard-plastic solution which just moves the cord breaking point farther from the adapter - The Fray Fix seems nearly impossible to install despite looking promising after that
