I first went backpacking in 1990, back then if you wanted to be a real backpacker you got a humongous Lowe Alpine teal and purple backpack. And pretty much people keep using them today. I love heading out in the back country and staying under stars. But I have a job and on top of that go to grad school. So I rarely if ever go out for more than one night. Yet I still carried a huge pack with a ton of gear in it.
Enter the Osprey Hornet 46, which literally changed the game for me. It is an ultra light backpack that has 46 liters of capacity and tons of small well thought out features. The bag is made of lightweight ripstop material, with lightweight straps and tons of compression points. It has mesh shoulder straps with large cutouts in the foam for lighter weight and increased breathability.
