The main compartment has a thin divider to help organize your gear and provide plenty of space to hold gear and even a large coat should you need to. Inside the bag are two small net style pockets mounted high on the sides for the storage of small items such as your MP3 player. These pockets have small access ports to run your headphones out of but no worries, they have velcro flaps to seal them. The bottom of the bag has a grommet hole for any spillage that might happen inside the bag. The hydration bag has its own compartment against your back and even has a strap to keep the bladder from collapsing into the bottom. There are 4 different hose ports in the bag giving you many options as to how you want to run the drinking tube. Oh and did I mention the tube came Insulated!
Externally the bag has much webbing for any accessories you may want to add. And it also has two zippered side pockets for easy access to small items and one of them has a built in organizer for small items like tools, pens etc.
This bag is well designed and very functional! The bags sholder straps and waist straps are heavily padded. The bag distributes even a heavy load very well, drastically reducing fatigue cased by pressure points. The portion of the bag against your back is well padded as well. All of this padding is the mesh style giving very good ventilation.
My overall impression of this bag is very good! Having used it in extreme cold and still finding it easy to use even w/ heavy gloves adds greatly to my satisfaction w/ this bag. It is a large bag so if you need a pack for short excursions this may not be the bag for you. But that does not necessarily mean you have to fill it. I will be using this bag through every season. I never tend to pack light and even if I do I like the simplicity of using just one bag. I chose the muticam because it fits our terrain better.
