This chart is designed to offer a better idea how a Nimrod pack interchanges with all other Nimrod gear and offers spec's, volumes, physical sizes and more info on each pack. We have a couple packs that will be added in this line-up in the future, including the Bugle pack, that is between the Pinnacle pack and the guide pack and the Flyweight pack, that is between the Base Belt and the Pinnacle. These have more info on their respective pages.
