🧼 Care & Maintenance Instructions

  1. Spot Cleaning: Wipe away small dirt spots or mud with a damp cloth and mild soap.
  2. Machine Washing: Clean in a front-loading washing machine on a gentle, cold water cycle. Do not use top loaders with agitators, as they can tear the stitching.
  3. Drying: Air dry flat out of direct sunlight, or tumble dry on the lowest possible heat setting with clean tennis balls to restore fiber fluffiness.
  4. Storage: Avoid storing the bag compressed inside its sack for long periods. Hang it loose in a dry closet to preserve the fill's thermal performance.

"We hit unexpected rain on our last camping trip and the tent floor got damp, but the 210T polyester shell kept me totally dry. The drawstring hood is a lifesaver for blocking out midnight drafts." — Sarah L.
