A well-made sweater can last for years—if you treat it right. Whether it’s wool, cashmere, cotton, or a synthetic blend, how you store it plays a major role in keeping its shape, softness, and color. Sweaters don’t just wear out from use; improper storage between seasons can also cause damage. Here’s how to make your sweaters last longer with a few simple but effective habits.

Clean and Prepare Before Storing

Before packing your sweaters away for the season, make sure they’re completely clean. Dirt, sweat, and body oils can break down fibers over time and attract moths. Always follow the care label instructions carefully.

• Wool and cashmere should be washed with a gentle wool detergent, ideally by hand or on a delicate cycle in cold water.
• Cotton and synthetic materials can usually handle machine washing, but avoid high heat, which can cause shrinking or loss of elasticity.
• Ensure sweaters are fully dry before storing—any moisture can lead to mildew or musty odors.

A good tip is to air them out after washing. Hang them flat on a drying rack or lay them on a clean towel to dry naturally. Avoid fabric softeners, which can coat fibers and reduce breathability.

Fold—Don’t Hang

It might seem convenient to hang sweaters, but gravity can stretch them out, especially at the shoulders. Instead, fold your sweaters and store them on a shelf or in a drawer.

If you must hang them, use wide, padded hangers and fold the sweater over the hanger’s bar to distribute the weight evenly. This is especially important for heavier knits like wool or alpaca.

Choose the Right Storage Spot

Temperature and humidity matter. Sweaters should be stored in a cool, dry, and dark place. Direct sunlight can fade colors, while damp basements or attics can cause mold and odor.

Use fabric or plastic storage bins with lids to protect against dust and pests. If you use plastic bins, make sure there’s some ventilation so the fibers can breathe. You can also place acid-free tissue paper between sweaters to prevent friction and creasing.

Protect Against Moths and Odors

Moths love natural fibers like wool and cashmere, but you can keep them away naturally. Add lavender sachets, cedar blocks, or bay leaves to your storage containers—they smell pleasant and deter insects. Avoid chemical mothballs, which can leave a strong odor and may damage fabrics.

If you’ve had moth issues before, place sweaters in a sealed plastic bag and freeze them for a few days before storing. The cold kills any eggs or larvae that might be present.

Air Out and Rotate

Even when stored properly, sweaters benefit from occasional airing. Take them out a few times a year, shake them gently, and let them breathe in fresh air. This helps prevent stiffness and keeps them smelling fresh.

If you own many sweaters, rotate them in use. Wearing different ones throughout the season reduces wear on any single piece and helps each sweater maintain its shape longer.

Seasonal Storage Tips

When winter ends and it’s time to put away your heavier knits, store them separately from your lighter summer clothes. If space is tight, you can use vacuum-sealed bags—but only for synthetic materials. Natural fibers like wool and cashmere need airflow to stay in good condition.

Label your storage bins or bags so you can easily find your favorites when the weather cools down again.
