Versatile bag

The pros:
- The possibilities of settings, both the size of the back on the breakdown.
- Location and hole for hydration pack.
- Integrated Rain protection.
- Extension + 4L fast thanks to a zip.
- Possible separation in the lower part of the bag (put dirty sleeping bag or shoes).

The -:
- No interior storage with zip. This is handy when the bag turns and thus avoid finding content mixed in the bag (currency, small objects, etc.).
- Better storage system of straps that are long.
- I would have preferred an abdominal strap slightly wider tightening.
