super rigid frame?
The aim of the multi section D2 frame is that it will FLEX as you move thus providing a more comfortable trek. If this pack is indeed RIGID then the new Jansport has missed the boat, and the point. Having examined the frame fittings on another page the hip belt loops are indeed attached with a metal to metal fitting, not the nylon bushings of the original issue D2. Perhaps wrapping the frame with teflon tape then attaching the hip loops will help with the reported noise.
Did anyone at the 'new Jansport' consult the original D2 designers or even LOOK AT an original D2? Some important details have been missed.
