i just ordered a KS ultralight KS 40 in the same VX07, but was really tempted by the Simple 40.
the KS 40 measures 15cm x 30cm x 75cm … I am a little concerned it might be too big. It seems pretty parallel size wise the the Simple 40 based on measurements. I have been volume crunching pack sizes and I think I am going nuts over 0.75 cm here and 0.40 cm there!
Also, I feel like there is really poor volume standardization across manufacturers so it has to be taken with a grain of salt.
