The Transformer complements Eberlestock's F1 Mainframe pack. It’s a lightweight, versatile pack that can stand alone, or can be piggy-backed on the Mainframe. With a full-featured layout that includes both top and front access, and two full-depth side pockets, the Transformer is made to appeal to those who are looking for Eberlestock quality combined with stripped-down, minimalist weight savings — while maintaining just enough functionality to stand as a great all-around pack. You can also add a hip-belt, or use the one off of the Mainframe, if you’re using the packs as a set. Don’t let all of the options confuse you; this is a very straightforward and versatile system with a unique and practical kind of modularity. You can build the pack that best suits your needs, or a system that allows you to pick-and-choose based on the demands of the moment, with each option providing a seamless functionality.
