i'm currently decluttering/minimalising my life.
i want to fit all my belongings in one backpack and sell all backpacks, including my most used backpacks, a lowe 70 liter and a thule 25 liter crossover.
i want to be able to use the backpack as my daypack, use it as carryon for flying w/o checking a bag, for hiking/adventuring, and to move all my stuff from a to b for a new place.
i learned that i don't need much, the smart alec with 26 liters is my current favorite, but my testpack has shown me, that my thule 25 is way too small. the alec has one additional liter, but i'm not sure if that's enough.
on the first photo is everything i now call essential minus my ordered vaio pro 13 and my nexus 4 and my earth runners sandals.
can you help me, i'm not sure if the smart alec will work, i really want it to work, the size seems ideal. plus i'm not sure which addons i should get, to maximise my portability and to be able to remove needed items quick while still staying organized and not have a huge pile of stuff, when i'm at a place where i wanna unpack and repack stuff for the day out.
the cache is a no brainer for the vaio pro, snake charmer looks useful too, not sure about the gate keeper straps, freudian slip, clear pouches.
not sure if i should get the addon modular pockets, will i still be able to take it on the place with them?
also is the smart alec waterproof/resistant?
here's my list with all my deemed essential belongings, if you have some ideas about reducing it even further w/o spending too much, i'm always thankful for advice:
jeantex sailing rain jacket
camelbak 2 liters
hiking shoes (waterproof, use them as winter shoes too)
earth runners sandals (not pictured)
2 pair short socks
2 pair long socks
1 pair wool socks
1 long pants
1 short pants
1 swimming pants
2 t-shirts / 1 polo
2 training/under shirts
1 dress shirt
1 super warm wool pullover
1 cashmere pullover
1 long warm underpants
1 long warm undershirt
small bag with toiletries
vaio pro 13
any help is really appreciated,
