The Pop Up 40 is a great pack! It is super comfortable in the field. I'm 6' and the large fits great. I was used to using a different brand of pack that had organizational pockets inside. This pack has none besides the top pouch. I was a little disappointed, but ordered some stash sacks and think that'll do the trick.
Really excited to use the meat hauling system. Seems easy enough to set up.
I love the size of the Pop Up 40. My brother has been using the metcalf for a while and loves it, but I knew that would be more than I needed.
Overall, definitely glad I went with Mystery Ranch and I would definitely buy it again.
