Futura Pro - the future in backpacks. The Aircomfort Futura Pro System brings together three key elements which work to full advantage when your dream trip necessitates carrying a bit more gear: top Aircomfort ventilation, flexible carry comfort and a nice, snug hip belt. The key to this clever combination lies in its frame construction and the floating VariFlex hip belt. Added to this are the specially tailored SL-shoulder straps and SL hip fins, advantages which will be especially appreciated by female Aircomfort fans.
