Trailblazer vs ADV skin

Hello!

I recently started running and some minor trail, mixed with nature walking.

I tend to pack a bit of things, because i like the adventure, of not knowing if it is gonna be 1 hour or 12; i get some snacks something to drink and some light jacket and or towel, usually for me and my gf/friend.

I saw in my local shop that salomon trailblazer 10 was discounted to 35 euros, but when i tried it felt a bit too small in space and did not felt that confortable or high quality.

So i ordered the trailblazer 20 for around 45 euros (also discounted).

Today i got it in my hands, and even tho it looks small from outside, inside is quite spacious, BUT still doesn't feel like would be comfortable to use it for my walks/runs/trails, and neither feel sturdy or with any structure.

So i was thinking about the ADV skin 12.

I see it being a bit bigger than trailblazer 10 (also have drink pockets outside the main bag so i save some space) , and i guess will be more comfortable to run on it.

I understand tat trailblazer is more like an everyday backpack, but i really thought even the 20l should feel better while moving. And i also understand that there should be better brands and even better prices, but i kinda love the aesthetics of having all outfit o the same brand/brand less, and mono colour.

Also, did anyone ever used ADV ski outside of specifically sport situations? Like in summer going somewhere outdoor, use it as a way to not carry anything in ur pockets as just a backpack vest?
