Are you the owner of a Baltro or Nuptse jacket? In my opinion, this item is the most suitable for cold protection as it extends to the lower back. The size feels like a men's L to M. Please check the size chart in the images. A great deal if the size fits! Purchased from Goldwin Japan. With tags. This is not from mass retailers, Korea, Vietnam, Don Quijote, or parallel import channels. The reason why some are so cheap is likely because they are older models or parallel imports. If you're going to buy one, I recommend one with the Goldwin tag. Goldwin products can also be repaired (repairs can be done through the Goldwin official website). Worn about 10 times. Size is in the images. Instant purchase available. Size S (US size) nd51901z
