Howdy,

You've come to the right place. Time for some tough luv

The tent, pack and sleeping bag need review for replacement, probably in that order (cut the pack after you've worked on the other big items so you can size it correctly). You have a filter plus UV. Pick one (probably UV plus a simple prefilter). You somehow have found a one pound spinning reel and in any case, can do with just the fly reel. Nalgene bottles are always overkill and can be replaced by reused lightweight drink containers from the store.

Only take the bear canister where required, otherwise learn tree hanging or consider an Ursack.

You can cut the rain jacket weight in half and your insulated jacket as well.

You've done well in a lot of other areas, your kitchen for example, so you're probably closer than you might think. Beginning with the tent, there's an easy ten pounds to shed without breaking a sweat. The next five will require more creativity, then voila, you're home free.

Cheers,
