Product review (5 stars): Little bag, BIG volume.
Great small bag for 2 or 3 days on the bike.  I have utilized mostly on my gravel / trail bike.  Used it traversing the Katy trail.  It fit two days of off bike clothes and two days of on bikes clothes during the fall.  So, mostly bib tights, base layers, long pants, flannel shirts, and light jackets.  In the middle "trunk" compartment is an insulated "lunch box" area.  I typically load it with a couple Monster drinks, snacks and spare tubes.  Great little bag for long day trip or 2 to 3 days on the trail.
