I bought the pack at the University of Minnesota Duluth Outdoor Program gear swap about 12 years ago and have taken it on exactly two BWCA trips. I grabbed it because the price was right, but it's just way more pack than I need. (Its volume is 155 liters / 9,420 cubic inches.)

Here's the official Duluth Pack description: https://www.duluthpack.com/backpacks/canoe-packs/paul-bunyan.html

I'd be very interested in working out a trade for a pack in similar condition that's somewhere between 75 and 90 liters. I'd prefer a true Duluth Pack, but I'd be interested in any Duluth-style pack, especially one with a flat bottom.

I can send more photos.
