I believe the pop up is a very niche design, and works better than anything within the small niche they are perfect for. They are a little sloppy when not full, I have the 18, so filling it has never been an issue.
The material seems like it would be loud, but in my experience, it’s not as loud as cordura while being worn, like going through brush, it’s quiet, it’s a more slippery material than cordura… neither bother me and I can keep them quiet when necessary
It’s almost like the pop up was custom made for chasing roosies with a bow, that’s their shining moment, very cool pack for that. Also a nice pack for calling lions in decent weather… run out of room quick with extra layers of clothes
It’s awesome in the brush, not getting hung up on your frame non stop, and can turn into a useful load hauler in seconds.
I wish they had more compression options, that’s it’s biggest downside for hauling meat, have to be careful loading the pack so meat isn’t able to squirt out the sides between compression straps
