Learn the right way to wash and care for cashmere and PrimaLoft® vests. Follow our step-by-step guide to keep them warm, soft, and looking great.

Quick Answer

To keep your cashmere and PrimaLoft® vests in top shape, always check the care label first. Hand wash cashmere in cold water with a gentle detergent, and machine wash PrimaLoft® vests on a delicate cycle. Air dry both to preserve their insulation and softness.

Vests are a versatile layering piece, whether you're heading to the office or out for a weekend hike. But when they're made from delicate fabrics like cashmere or insulated with PrimaLoft®, proper care is essential to keep them performing and looking their best.

In this guide, we'll walk you through the specific washing and drying steps for both cashmere and PrimaLoft® vests. You'll also learn common mistakes to avoid and how to store them correctly, so your investment lasts for years.

Understanding Your Vest's Fabric

Cashmere is a natural, luxurious fiber known for its incredible softness and warmth. However, it's also delicate and prone to shrinking or felting if washed too aggressively. On the other hand, PrimaLoft® is a synthetic insulation designed to mimic down while retaining heat even when wet. It's more durable and easier to care for, but still requires gentle handling to maintain its loft.

Before you do anything, always read the care label on your vest. Some cashmere blends may be machine washable, but pure cashmere usually needs hand washing. PrimaLoft® vests are typically machine washable, but using the wrong cycle or detergent can damage the insulation.

  • Check the care label for specific instructions and temperature recommendations.
  • Test a small, hidden area for colorfastness if you're unsure about washing.

Washing Cashmere Vests

Hand washing is the safest method for cashmere. Fill a basin with cold water and add a small amount of pH-neutral, wool-safe detergent. Submerge the vest and gently press it down—do not rub or wring. Let it soak for about 10 minutes, then rinse thoroughly with cold water until no soap remains.

If your cashmere vest's label allows machine washing, use a mesh laundry bag and select the delicate or wool cycle with cold water. Use a detergent specifically formulated for wool or delicates. Never use bleach or fabric softeners, as they can break down the fibers.

  • Always use cold water to prevent shrinking.
  • Never wring or twist cashmere; press out excess water gently.

Washing PrimaLoft® Vests

PrimaLoft® vests are more forgiving. You can machine wash them on a gentle cycle with cold or warm water. Use a mild liquid detergent—avoid powders that might leave residue. Turn the vest inside out and fasten any zippers to prevent snagging. Wash with similar colors to avoid dye transfer.

If your vest has a water-repellent finish, you can use a technical wash product to help maintain its performance. However, avoid fabric softeners and dryer sheets, as they can clog the pores of the insulation and reduce breathability.

  • Close all zippers and Velcro before washing.
  • Use a front-loading machine if possible; top-loaders with agitators can be harsh.

Drying and Storing Your Vests

Both cashmere and PrimaLoft® vests should be air-dried. Lay cashmere flat on a clean towel, reshaping it to its original dimensions. Keep it away from direct sunlight and heat sources. PrimaLoft® vests can be hung to dry or laid flat. Never tumble dry unless the label specifically says it's safe, as high heat can damage synthetic fibers.

Once dry, store your vests properly. Fold cashmere and place it in a drawer or on a shelf—hanging can stretch the shoulders. PrimaLoft® vests can be hung, but use a padded hanger to maintain shape. Keep them in a cool, dry place away from moths and moisture.

  • For cashmere, consider using cedar blocks or lavender sachets to deter moths.
  • Avoid storing vests in plastic bags; use breathable garment bags instead.

Step-by-Step Vest Care Routine

  1. Read the Care Label: Always check the manufacturer's instructions for specific washing and drying recommendations. This is your first line of defense against damage. Checkpoint: If the label says 'dry clean only,' don't risk hand washing.
  2. Pre-Treat Stains Gently: Spot clean any stains with a mild detergent and a soft cloth before washing. Avoid rubbing vigorously, as this can damage the fabric. Checkpoint: Test the detergent on an inconspicuous area first.
  3. Wash with Care: For cashmere, hand wash in cold water with a wool-safe detergent. For PrimaLoft®, machine wash on delicate with cold water and mild detergent. Never use hot water or harsh chemicals like bleach.
  4. Rinse Thoroughly: Ensure all detergent is completely removed. Residual soap can attract dirt and cause skin irritation. Checkpoint: Rinse until the water runs clear.
  5. Dry Flat or Hang: Lay cashmere flat on a towel to dry. Hang PrimaLoft® vests or lay them flat, away from direct heat. Avoid wringing or twisting; press out excess water gently.
  6. Store Properly: Fold cashmere and store in a drawer. Hang PrimaLoft® vests on padded hangers. Keep in a cool, dry place. Use breathable storage to prevent moisture buildup.
