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 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. It's a hard-to-find item now, so if you were looking for one, 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, you'll love this.
