Help me lighten my pack weight

[u/dan_thewoodsman]

On my last 4 day trip my total weight was around 40lbs that’s with water and food included. I used this app to figure out my base weight was around 27lbs, which to me seems ridiculous. Like the title says, what can I swap out or get rid of entirely to get this weight down slightly? (The pack is non negotiable, as comfort is a priority for me on long days on the trail) thanks

Replace the two Nalgene with one of the bags linked. Just used one for a three day trip in the BWCA, and with the 2l sawyer squeeze dirty bag it works amazingly well. Make sure you pack the syringe for back flushing- it got really slow after about 4-5l of water filtering, and needed back flushing at least once a day.
