This G4Free pack has a frame and a bottom pocket/entry for quick access to your sleeping bag and a hidden pack cover compartment. Plenty of pockets but the side pockets were kinda thingy and the back pockets were kinda blah. Plenty of straps that make it seem pro but in real life is a waste.G4Free 50LMy first real pack… I remember that first hike; this was awful. Sure the pack is large and functional but it’s heavy and the side pockets are sticky and small. Since it’s waterproof if anything is wet and then put in the pack then it all get’s wet.More useless drybags… at least no hiking use-case that comes to mind.
