New With Tag. Ice Dye Moss Green. Nulux fabric is sleek, buttery soft, lightweight, friction-free coverage with a COOL FEEL. The Nulux Define Jacket is a different material than the regular Define Jacket. Besides the pattern, I do love how it has the ability to feel cool to the touch. I already have one so that is why I'm selling it. In perfect condition and flawless. Comes from non-smoking home and no pets.
