Don't vacuum-seal your cashmere or down coats

Vacuum storage bags are risky for delicate fabrics and certain winter coats — especially in small closets where you’re already fighting for space.

The problem is compression. Down jackets rely on trapped air for insulation. Shove one in a vacuum bag and you crush the feathers; they may never fully loft again. I’ve seen it happen — a puffy that came out flat and never recovered, no matter how long I fluffed it. Same goes for anything with natural fill (wool, silk, cashmere).
