Perfect replacement

I've put it through the wringer

I needed to replace my old Blackburn under seat bag after 17 years of MTB use. Can?t complain one bit. I wanted another small bag for keys and micro tool and this is another perfect bag for when I don?t want to grab a larger back pack. I would recommend this bag for similar use.

I've put it through the wringer

Have the medium size and it fits a m19 multitool, co2 inflator, phone, and keys juuust barely. Water in the cage and then voile strap a tube and co2 to the frame and you are good to go for anything under ~2 hours with no annoying packs on your body
