Not much, especially when referring to the legs, but some would be on your arms and shoulders, more on your "center" whereas in the pack it would be more weight off of your center. I know that with 3 prior back surgeries, the closer the load is to my center, the easier it is for me, no matter the quality of my pack.
Ps I wouldn't recommend wearing it in a kayak in case you bail: it gets really heavy when wet!
