I have this bag or at least a similar model same brand, it holds my entire hammock sleep system, food, backwoods gear, clothes, and tools. It supports it comfortably while climbing, hiking, running, and carrying a canoe or w/e.

Comes with a rain cover, moisture kills.

Fill the bag and your brain right and you could last from june till mid september in the right environment. For 4 season, I strap another 20L back to the top of this bag. But its too damn cold where i am to last without a good shelter.

I have a really nice list if you want to take a looksie, maybe ill even do a little workup on this sub.
