Hi,
In short...saving weight in the pack...yes....worth it...
Cause we are not talking grams when it comes to pack weights.
Although all this weight saving comes at a cost, light weight costs more....
Started writing very little and then got carried away...
Others are talking about 1, 2 or even 3kg.....for packs.....
We are in an UL part of the forum, my main pack weighs 500g, an Arc Blast around 55 lt.
Use it for any overnight, mulitday trip, framed, comfortable, great, never run out of room.
If we are talking comfort...then the less on my back makes for more comfort and enjoyment which is part of the reason to go for a walk.
A 2.5 kg pack on your back before you have put any gear in it...
By that weight I have my pack(500), 2 person tent(1200) (Tarptent Stratospire II), cooking gear(450), sleeping mat(250).......and that is my luxury mat...I have a lighter one
I can cut that down if it is just me on my own.
It is also all the other gear you reduce weight on too, you then choose lighter and more compact items across your whole kit.
Weight also depends on where you hike.
Hard to drop some weight if you are in Tasmania as have weather factors to consider.
It is part philosopy.
Part of the process is also to eliminate all those items you may take but actually do not require, call it minimalist if you like.
You look for items that serve multiple purposes.
I still carry first aid, PLB, compass, battery pack, phone, camera etc. and a range of items.
Do you actually need the full cutlery set if you have a spork and a multitool with knife, and my multitool weighs 46g.
How many pots/cups do you need when 1 will do and the lid is your cup.
What does your stove look like....I have a few.....range from 45 g to 100g.
Alfoil works great as a wind/heat shield and weighs nothing....have been using the same piece now for over 5 years.....fold it up and stick it in the pot bag.
I eat well, tend to use Strive food packs, low weight for calorie supply, quality, have good vego options as do not eat meat.
Dried fruit and nut mixes, fresh banana, mandarin, apples(come in their own packaging).
Would rarely weigh in above 14kg for multiday walk.
Often between 11 and 12kg.
Only if have to carry significant water supply.
There are others here that would be even less weight than me by kg's.
YMMV
