You’ll pedal in comfort with the foam framesheet spreading the load across a ventilated mesh backpanel. The BioStretch™ shoulder harness provides a contoured fit. The webbing hipbelt is removable to shave ounces while upper and lower side compression straps offer additional stability if you’re carrying extra weight.
