An absolutely incredible pack. Light enough to be my overnight pack, but flexible enough and with enough volume (I love the rolltop for this) and external expandability that I could easily take this on a much longer trek. They've updated the design somewhat since some of the reviews on Youtube, specifically Taylor Passofaro's video, including two full hip belt pockets (old model had one pocket and one stretchy mesh pocket) and more attachment loops that extend farther down along the sides of the pack, allowing you to adjust the placement of the included bungie cord if you want. This is my first frameless pack, so I packed carefully to make sure nothing stuck into my back, and it was supremely comfortable. I forgot I was wearing it at times, even with ~20+ lbs in the pack. And the removable cushion!!! Holy cow, what a game changer. Easy to pop out and pop back in on breaks or for lunch, and it saves you needing to pack any sort of ground protection or camp chair for when you get to camp. 10/10!
