I just purchased one of these from MEC. It's by no means the worlds best pack but thought it looked like a great bag for fast day scrambles when I bring harness, axe and rope and could also do even up to 3 days backpacking.
Super cheap, light and customisable to be even lighter and comes with the MEC warranty (Don't like it return it). Great for those of us without access to a sewing machine to make a wicked light pack.
What do you guys think?
