We designed the Ibex to fill in a gap we felt was missing from our pack systems. It's designed to be very versatile. We incorporated a modular system on the bag to allow for external pockets to be add. The hunter can configure the bag to fit their needs. You can use it for a weekend hunt or a 7 day hunt.
