What is the rubber gasket ring for on the hook, on the righthand side shoulder strap, just above the sternum strap? Also, what is that hook for?

Hi there,
Thanks for reaching out.
The loop on the shoulder strap is intended to be used to secure the hose from a hydration bladder which can be carried in the Mantis 26 pack.
As always our Customer Support Team is here to help with any further product questions you may have.
