It's not intended to be packed but is made from virtually the made material as the now discontinued Actuator which has an integrated stuff pouch. I would recommend against storing the jacket like that for extended times as creases -nothing wearing it won't fix- will form and detract from the fluid aesthetic. I wouldn't worry about permanent damage since it's Goretex. Veilance sleeves are chronically long. I'm 5'8 and and swim in my sleeves. The Monitor cuffs are moulded and I find the additional length not to be a problem.
