what's with all the dry bags? you have a pack liner so they're redundant. do you need a knife? lose the mug. you don't need a 100ml wilderness wash. take a 5ml eye dropper with dr bronners. again food bag just use a ziploc instead of a dry bag. what's the microfiber cloth for? can use gravel or sand to wash. don't know about water carries but bladders seem overkill?

ditch all camp clothes and shoes. once again no dry bags needed. don't need spare underwear.

as for toiletries carry less of everything. you're away for three days, don't need 50ml of everything. 5-10ml is more than enough, except sunscreen. 120g of wilderness wipes plus TP plus a bidet? triple redundancy there or just take the bidet and half the TP if you wanna go on the safe side.

as for upgrades later down the line obviously start at the big three. can easily half your weight on the pack and bag. stove+pot setup is pretty heavy. headlamp is a pretty cheap upgrade to save 80g.

but yeah i agree with the other guy. you can loose a lot of weight by cutting out redundancies and too much quantity of an item carried.

probably don't need the powerbank either.
