Half frame bag procaliber 8

Hi everyone,

I’m looking for a slim frame bag for my Trek Procaliber 8 (2026). I don’t want a full-frame bag—just something compact that still lets me use the lower water bottle.

I tried the Geosmina MTB Small, but it felt a bit too bulky for my setup. I mainly want to carry tools and essentials for longer rides, so it doesn’t need to have a lot of capacity.

Any recommendations? Maybe even something that fits the Trek particularly well?

Thanks in advance!
