In the military we could carry a full large duffel bag on our bag and another on our back. But it wouldn't be anything you would want to do anywhere near a battlefield. You shuffled along. I would say make it an Impossible difficulty to attack anything and give attackers a huge bonus to attack them in melee.

I served 30 years in the French Navy, I know well how you can easily be over encumbered.
