Hey Tyler. I did pick up a summit pack off gear swap. I like a lot of things about it, but not sure its going to work for my current needs. What exactly you plan to use it for? It probably would make a great day pack and general around town. I used mine on an overnight backpacking trip. I was carrying a bit more than I needed as I was testing some gear and also wasn't sure how long I'd stay out. I found it a bit uncomfortable towards the end of my hike, but it may have been on the upper end of its weight limit. I haven't tested it yet with a more standard pack out. I decided I want my pack in that size range to be more geared towards running and fastpacking as that is what my short trips will tend to be.
If you've ever used an HMG pack, they have a lot of things going for them. I love their simplicity for packing and the roll top / compression system is my favorite (I have a 3400 porter). I prefer their 150d fabric as its pretty bomber.
Let me know if you have any questions. I may load mine up with my standard kit just to see what I think.
