This is a roomy 5500 cubic inch (90L) backpacking pack. It has a front access via two full length zippers and an internal compression system that works very well. The materials are incredibly rugged and durable. The brain fully detaches and can be worn as a waist pack. 

I've had it for quite some time but I no longer use it as I have another pack that works better for my aged body.

Asking $60 plus shipping, though a local handoff in the Davis/Sacramento Area would be better. I also climb frequently in the Bishop and Sonora areas and could arrange a handoff.

The frame is size medium and fits me well - skinny 5'9" guy.
