Title: You get what you pay for.
Review: This is a very cheap product and this is how it performs. The mouth guard fell off on the first use, and the reservoir never sealed perfectly. But the biggest problem is that when running, the Alterra really messes up your stride. It is advertised as a running hydration pack but it is COMPLETELY unsuitable for this. It would work well for hiking or maybe biking (I didn't try this), but DO NOT buy it for running!
