​CONDITION REPORT

​[ak] Japan 457 Micro Fleece:

• ​Status: Pristine.

• ​Details: This item remains in "Vault" condition. No pilling, thinning, or loss of structural elasticity. Zippers and hardware are factory-sharp.

​[ak] Japan GORE-TEX PRO 457 Guide Jacket:

• ​Status: Used / Excellent.

• ​Integrity: Structurally pristine. All GORE-SEAM tape is perfectly intact; technical membranes and zippers are 100% functional.

• ​Aesthetic Note: As this is a genuine high-alpine tool, the white panels show light discoloration/color migration from use. This is purely cosmetic and typical of the Plum/White colorway; it does not compromise the technical performance of the GORE-TEX Pro shell. Both items have been professionally washed to maintain DWR (Durable Water Repellent) integrity.
