To clarify the modularity of the ICON Pro and ULTRA pack lines, below is an explanation of how these packs work as one system built off the same frame.
The ICON Pro and ULTRA bags and suspension are completely interchangeable. By purchasing either an ICON Pro or ULTRA full kit (Bag, Frame, and Suspension) there is no need to purchase another full kit to switch pack lines. Both the ICON Pro and ULTRA packs are built off the same 11 oz California made carbon fiber frame. The frame comes in 2 different sizes (Regular & Tall) to fit torso lengths from 15″ – 22″. Because this frame is the foundation for both pack lines, only one frame is necessary for all 7 bag configurations.
For example: By purchasing an ICON Pro 1850 full kit, you receive the Frame, Pro Suspension (shoulder straps and waist belt), and the Pro 1850 bag. If you then purchase the ULTRA 6000 “Bag Only”, that bag will fit onto the Frame and Pro Suspension for a modular setup. The only modification that is necessary to make the two compatible is switching the compression strap buckles to match the style used for each bag, which is only a couple minute procedure. The buckles needed for this are shipped with each “bag only” order.
