SIMPLE PERFECTION in an ULTRA-LIGHT trekking pack. Too often load carrying performance is compromised in the design of a lightweight pack. This is not a compromise we are comfortable making. This model gets its name from Occam's Razor, the idea that "simple explanations are generally better than more complex ones". In this case we have the simplicity of a clean and classically flared bag carried on an outwardly simple but cunningly engineered back system. It is up to you to decide how to set up the bag. Choose the optional module for water bottle pockets, tool racking and compression, or go the other way and remove the hip wings for a truly minimalist lightweight sack.
