Guys, need some infos from someone who has tried this. Going to downsize to a Crossfire2 139 and am curious if it will fit in my Icon I5 or be too small. I have jumped a pilot 168 ZPX, which is a fair fit, Sabre2 150 (which packs a bit bigger than the Pilot) and was wondering about the pack volume of a Crossfire2 139 compared to the Sabre2 150. Has anyone tried and can tell me if it's an OK fit, loose fit (which it should be) or a too loose fit? Thx D
