While one can go lighter....if you like the gear and it is paid for what you might consider is looking at everything you take. Very carefully. And see if there are things you don't actually need, but are 'luxury' items.

What I do is run a spread sheet of everything I might possibly take with its measured weight.

Then I know exactly what my pack will weigh!

Adding water could bump you up 6 lbs or more...and food? 2 to 6 lbs. So you can see hitting 30 lbs won't be much work.
