Building off the successes of the Crown2, the Crown3 60 boasts Granite Gear's fully adjustable Re-Fit hip belt, a new and innovative Vapor Current Mark 3 compression molded PE frame sheet with molded foam back panel, and removable lid (which converts into a chest pack or lumbar pack in conjunction with the hip belt), all while weighing in at 2.4lbs (regular torso without lid). For ultralight loads, the frame sheet can be removed, lowering the weight to 2lbs.

　　The Vapor Current Mark 3 compression molded polyethylene frame sheet has molded reinforcement channels and die-cut holes to minimize weight without sacrificing structural integrity. The frame works in combination with the molded foam back panel with ventilation channels to support an efficient load transfer of 35lbs comfortably. The frame sheet is fully removable for weight savings when the base weight of the pack doesn't call it.

　　New for the Crown3 is the optional add-on capability of reinforcing the frame sheet with a U-shaped aluminum stay for treks that do require base weights north of 35lbs (sold separately).
