At the beginning I was more than convinced of the Camelback. Clear the storage space is small, but I was already aware of the purchase and not a big deal. The backpack was used for mountain biking (no crashes). On longer trips, there is nothing more pleasant than it was to have water reserves on the back.

After 4 months of use (with water) but raises the following problem:

The opening of the bladder for filling can be almost impossible to close. It acts as if wedged something. When it then creates times to close this, the bladder is nearly empty. Probably it is the rubber seal. Aufjedenfall the bladder is no longer usable.
