Quick Answer

To prevent snags in mesh underwear, always hand wash in cold water with a gentle detergent, avoid washing with items that have hooks or zippers, and never wring or tumble dry. Air drying flat or hanging by the waistband keeps the delicate fabric intact and extends its life significantly.

Why Mesh Underwear Snags So Easily

Mesh underwear, like the ultra lightweight Italian mesh used in On Gossamer styles, is made from fine nylon filaments woven into an open structure. That openness gives you breathability and an invisible look under clothes, but it also means individual threads are more exposed to friction and sharp edges. A single wash cycle with a bra hook, zipper, or rough denim can pull a thread and create a visible run or hole.

What to Avoid in the Laundry Routine

The biggest threats to mesh underwear are high heat, agitation, and contact with hardware. Machine washing on any cycle can cause the mesh to stretch, snag, or pill, especially if the load includes items with metal hooks, buttons, or zippers. Fabric softeners and bleach also weaken nylon fibers over time, making them more prone to tearing. Even the dryer's tumbling action can catch a thread and pull it out of alignment.

Step-by-Step Mesh Underwear Care Routine

  1. Step 1: Sort and Protect: Separate mesh underwear from any items with hooks, zippers, buttons, or rough textures like denim and towels. If you must machine wash, place each pair in a mesh laundry bag with a fine weave. A common mistake is tossing them in with a mixed load—one bra hook can ruin a pair. Checkpoint: Run your hand over every item in the load. If it feels rough or has hardware, keep it out.
  2. Step 2: Hand Wash in Cold Water: Fill a basin with cold water and add a small amount of mild, bleach-free detergent. Submerge the underwear and gently swish for about 30 seconds. Do not rub, scrub, or twist the fabric. Let it soak for 5 minutes if needed, then rinse with fresh cold water until no suds remain. Common mistake: Using warm or hot water can weaken the nylon mesh and cause it to lose elasticity over time.
  3. Step 3: Remove Excess Water Without Wringing: Lift the wet underwear out of the basin and gently press it between two clean, dry towels to absorb moisture. Never wring or twist the fabric—this distorts the mesh and can snap threads. Rolling the underwear in the towel and pressing works best. Checkpoint: If you see water dripping, press again with a fresh towel section until it's just damp.
  4. Step 4: Air Dry Flat or Hang by Waistband: Lay the underwear flat on a drying rack or hang it by the waistband using a plastic or padded hanger. Avoid clothespins that can pinch and snag the mesh. Mesh like On Gossamer's Italian nylon dries in under 8 minutes, so you don't need heat. Never put mesh underwear in the dryer. Common mistake: Hanging by the gusset or leg opening can stretch the mesh unevenly. Always hang by the waistband or lay flat.
  5. Step 5: Store With Care: Once fully dry, fold the underwear gently and store it in a drawer without heavy items on top. Avoid storing with Velcro, lace trims, or rough fabrics that could catch the mesh. A dedicated lingerie organizer or soft pouch works well. Checkpoint: Before folding, inspect the mesh for any loose threads. If you see one, carefully trim it with small scissors—never pull it.
