There is no fixed expiration date for pajamas: how long a set lasts depends on the fabric, how often you wear it and, above all, how you wash and dry it. Replace a set when it shows wear that care can no longer fix, such as fabric worn thin, holes or split seams, waistbands that no longer hold, or pilling that comes back again and again.
Here is what shortens the life of sleepwear, the signs to watch for and the habits that help your favorite set last.
What affects how long pajamas last
- How often you wash them. The U.S. Environmental Protection Agency advises against washing clothes after every use, noting that it lengthens their lifespan.
- How you wash and dry them. Metro Vancouver's clothing care guidance recommends the coldest, gentlest wash cycle you can use, and says hanging clothes to dry helps preserve their quality and extend their life.
- Friction. Pilling forms when wear and washing loosen fibers that then tangle into small balls on the surface. Pilling is caused by rubbing and abrasion, which is why it shows up first where fabric rubs most.
- Following the label. Under the U.S. Federal Trade Commission's Care Labeling Rule, care labels must state the regular care a garment needs and warn against procedures that would harm it. The label is the best guide to keeping a specific piece in good shape.
Signs it is time to replace your pajamas
| Sign | What you will notice | Can care fix it? |
|---|---|---|
| Light pilling | Small balls of fiber in high-friction spots | Often; remove pills gently and wash inside out going forward |
| Pilling that keeps reappearing | The surface looks fuzzy again soon after you remove pills | Rarely; the fabric surface is wearing down |
| Thin or see-through fabric | Light shows through the seat, knees or elbows | No; it is time for a new set |
| Holes or split seams | Small holes, or seams pulling apart | A small seam can be mended; holes in worn fabric tend to reappear |
| Tired waistband | The waistband no longer stays up | Usually not without replacing the elastic |
| Faded or uneven color | Color looks washed out in patches | No, though it may not affect comfort |
Care habits that help pajamas last longer
Eberjey's care guide, which Eberjey wrote to help garments live a long, soft life, recommends a few simple habits:
- Turn pieces inside out before washing to protect buttons, trims and prints and preserve the fabric's surface.
- Use a 30°C/86°F mild fine wash for TENCEL™ Modal, with a reduced load and little or no spinning to minimize creasing.
- Remove pieces promptly after washing to help maintain color and prevent transfer between contrast panels.
- Dry gently. Line dry or dry flat where the label allows, and if you tumble dry, choose a gentle cycle with reduced heat and a shorter time.

Rotate your sets
Because washing less often helps clothes last, having two or three sets in rotation means each one goes through the wash less frequently. Our article on how often to wash your pajamas looks at how to balance freshness with fabric care.
Choosing sets made to be worn often
When you do replace a set, choose fabric and construction you will want to wear every night. The Gisele TENCEL™ Modal Long PJ Set ($158, sizes XXS–XXL) is made from TENCEL™ Modal and a touch of elastane, verified by OEKO-TEX® Standard 100. If you prefer a roomier fit, the Gisele TENCEL™ Modal Slouchy PJ Set ($148, sizes XXS–XL) comes in TENCEL™ Modal, which Eberjey notes is machine washable. For a silk option you can wash at home, the Inez Washable Silk Long PJ Set ($298, sizes XS–XL) is made from 100% mulberry silk produced using bluesign®-certified processes. Our article on which fabrics pill the most explains what to look for in a fabric if pilling is your main concern.
