Eberlestock takes the frame pack to new levels with their Eberlestock Modular System (EMOD). The EMOD system features packs that can be mated together, and accessories that serve multiple functions allowing you to build the perfect system for your needs.
The mainframe features a tubular aluminum frame for excellent durability and strength. With a 700lb rating the mainframe is one of the most durable pack frames on the market.
Combine the Mainframe with the Eberlestock Little Brother pack to instantly convert the little brother to a frame pack for heavier loads. Or add bat wings for a lightweigh frame pack if you need to go in light and come out heavy.
The Mainframe pack frame and the EMOD systems allow you to build the perfect pack for the mission you are on.
