Storing a Sleeping Bag So It Lasts Ten Years

The way you store a sleeping bag matters more than how you wash it. Cramming a down bag into its stuff sack for months flattens the loft, and a flat bag is a cold bag.

Give your bag a chance to last.

• Store it loose in a large mesh or cotton sack, never compressed
• Hang it or drape it so the insulation can rebound
• Dry it fully before long-term storage to stop mildew
• Wash with down-specific soap only when it smells

A bag stored loose for a decade still puffs up on night one. One stored compressed loses loft in a single winter and never fully recovers.

Set a calendar reminder to hang your bag out every spring. Ten years of weekend trips come down to a bag that was never crushed between adventures.
