The Osprey Viper 13 is the largest of the Viper Series with 800 cubic inches of storage capacity, a decent amount for sure. It’s big enough for many day-long rides yet small enough to be considered a marathon pack. With the proven 3L large mouth Hydraform bladder you get one of the best bladders on the market plus key compartments to help you organize your gear. The large hose and decent bite valve on the included bladder both work great and the reservoir didn’t leak on me. The bladder, which I can’t rave about enough, works, fits, and cleans well. The molded form ensures that even if filled to the brim with water, you don’t feel like there’s a salami on your back.
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.
