This is a hybrid vest from System A, which was sold exclusively at specific stores like Beams and Arc'teryx Shinjuku and immediately sold out. It's useful for slightly chilly weather right now, or as an inner layer in mid-winter. Purchased at Beams, the tags have been removed, but it's in excellent condition, only tried on. This item is no longer available, so if you were looking for it, don't miss out. The size is M, with a length of approximately 64cm, shoulder width of approximately 44cm, and a body width of approximately 55cm. If you like Veilance, Tilak, or Poutnik, this is for you.
