To stop leggings from pilling, turn them inside out before washing, use a gentle cycle with cold water, skip fabric softener, and air dry. Choose leggings with tightly woven fabrics like nylon or spandex blends. For existing pilling, use a fabric shaver or sweater stone carefully.
Nothing ruins the look of your favorite leggings faster than those little fuzz balls known as pills. They make even expensive activewear look worn and cheap. But pilling isn’t inevitable. With a few smart habits and a little know-how, you can keep your leggings smooth and like new for months longer. Here’s the honest, practical guide to stopping pilling before it starts.
What causes leggings to pill?
Pilling happens when short fibers in the fabric break, tangle, and ball up on the surface. It’s most common in blends with cotton or low-quality synthetics. Friction is the main trigger: thighs rubbing together during walking or running, friction from a bag strap, or rough surfaces like gym benches and car seats. Laundry is another big culprit. Aggressive washing, hot water, and the tumbling action of a dryer all accelerate fiber wear. Fabric softener is especially bad because it coats fibers, making them slippery so they break more easily.
The fabric itself matters too. Knits with a looser weave, like some brushed polyester or cotton blends, pill faster than tightly woven nylon or spandex. Moisture-wicking treatments can also degrade over time, exposing short fibers. Understanding these causes helps you target your prevention efforts.
Choose leggings made to resist pilling
Your first line of defense is buying leggings with pilling-resistant fabrics. Look for high percentages of nylon or polyester (70% or more) blended with elastane or spandex. Nylon is inherently stronger than polyester and resists abrasion better. Tightly woven fabrics with a smooth surface are less likely to pill. Avoid cotton-heavy blends for activewear, as cotton fibers are short and prone to breaking.
Check the fabric content on the tag. Some brands also use anti-pilling treatments, but those can wear off. The best long-term bet is a dense, high-denier nylon or polyester. If you’re shopping online, look for reviews that mention durability and pilling resistance. And remember: a higher price doesn’t always guarantee better pilling performance, but cheap fabrics often have lower quality fibers that pill quickly.
Wash your leggings correctly
How you wash your leggings makes a huge difference. Always turn them inside out before washing. This protects the outer surface from direct friction against other clothes and the machine drum. Wash on a gentle or delicate cycle with cold water. Hot water weakens synthetic fibers and increases fraying. Use a mild liquid detergent; powders can be abrasive and leave residue. Skip fabric softener and dryer sheets entirely they break down fibers and reduce moisture wicking.
Don’t overload the washing machine. Give your leggings room to move without rubbing too hard against each other. For extra protection, put them in a mesh laundry bag. If you have just a few pairs, wash them together with similar items like other activewear or smooth fabrics. Avoid washing with items that have zippers, hooks, or rough textures that could snag.
Dry and store leggings with care
Heat is a major enemy of leggings. The best way to dry them is to lay them flat on a drying rack or a clean towel away from direct sunlight and heat sources. Air drying preserves fiber integrity. If you must use a dryer, use the lowest heat setting possible (like air fluff or no heat) and remove them while still slightly damp. But honestly, air drying is the safest way to extend their life.
When storing, fold leggings rather than hanging them. Hanging can stretch the fabric and cause friction at the hanger contact points. Store them in a drawer or shelf where they won’t be squished under heavy items. Avoid storing in direct sunlight, which can degrade synthetic fibers over time. Proper storage keeps the fabric relaxed and less prone to abrasion.
How to remove existing pilling
If your leggings already have pills, don’t despair. A fabric shaver (or sweater shaver) is the most effective tool. Lay the leggings flat on a hard surface, stretch the fabric gently, and run the shaver over the pilled areas with light pressure. Go slowly to avoid cutting the fabric. Test on an inconspicuous area first. For a gentler approach, use a sweater stone (a pumice-like block) and rub in one direction. A disposable razor can work in a pinch same gentle motion.
After shaving, wash and dry as usual to remove loose fibers. Be aware that shaving can weaken the fabric slightly if done too often, so it’s best to prevent pilling in the first place. If a pair keeps pilling after shaving more than once or twice, the fabric quality may be too low to save. In that case, consider them for low friction activities or replace them with better quality leggings.
Frequently asked questions
Can pilled leggings be fixed?
Yes, you can remove pills with a fabric shaver, sweater stone, or even a disposable razor. However, this only removes existing pills and may weaken the fabric with repeated use. Prevention is more effective.
Does dryer heat cause pilling?
Absolutely. High heat weakens synthetic fibers, making them more prone to breakage and pilling. Air drying is best, but if you must use a dryer, choose the lowest heat or no heat setting.
Are certain leggings materials less likely to pill?
Nylon and high-denier polyester blends (with spandex) are more resistant to pilling than cotton or low-quality polyester. Tightly woven, smooth fabrics also resist pilling better.
How often should you wash leggings?
Wash after every wear to remove sweat and oils that can degrade fibers. But use a gentle cycle and cold water to minimize wear. For light use, airing them out between wears can help reduce washing frequency.
