Natural elastic is a durable option for most garment uses and, when chosen well and cared for properly, performs comparably to high-quality synthetic elastic.
A common concern when switching from synthetic to natural materials is whether they will still “do the job.” We’ve been taught that synthetics equal durability — but the reality is more nuanced.
Like all elastic, lifespan depends not just on whether it’s natural or synthetic, but also how it’s made, how it’s used, and how it’s cared for. And there’s one important question often missing from the conversation: what happens to the elastic once it’s done its job?
DOES NATURAL ELASTIC LAST AS LONG AS SYNTHETIC ELASTIC?
High-quality synthetic elastics are engineered for performance and can offer excellent stretch and recovery over time. But “synthetic” isn’t a guarantee of durability — quality varies hugely.
Some elastics hold their stretch for years, while others quickly lose recovery, twist, or degrade after repeated washing and wear.
High-quality natural elastic, like the elastic we source, offers a different balance. When well made, it provides reliable stretch and recovery suitable for everyday garments, with durability comparable to quality synthetic options — without the long-term environmental impact of plastic-based fibres.
WHAT AFFECTS THE LIFESPAN OF ELASTIC
The biggest factor in how long elastic lasts is not just the material, but how it is used and cared for.
Key factors include:
- Quality of manufacture – Higher quality elastic will always perform better and last longer, regardless of type
- Stretch tension – Elastic that is consistently overstretched (either during sewing or during wear) will degrade faster
- Heat exposure – High heat (irons and tumble dryers) can significantly reduce lifespan
- Washing conditions – Frequent hot washes or harsh detergents can accelerate breakdown
WHERE NATURAL ELASTIC PERFORMS BEST
Natural elastic is well suited to most everyday garment applications, including:
- Waistbands (pyjamas, skirts, trousers)
- Underwear and next-to-skin garments
- Light to medium stretch applications
For high-performance uses — like lycra based sportswear, swimwear, or garments exposed to chlorine or saltwater — synthetic elastics may still be the better choice.
HOW TO MAKE YOUR ELASTIC LAST LONGER
If you want to get the most life out of your elastic:
- Avoid overstretching during sewing and wear
- Do not tumble dry (air drying is best)
- Wash at lower temperatures where possible
- Choose the right elastic for the application, not just the cheapest option
- Use a casing to protect your elastic or if using against the skin choose the right elastic type (see below)
ELASTIC AND HEAT
Heat is one of the quickest ways to shorten the lifespan of elastic.
Synthetic elastics can deform or lose elasticity when exposed to high temperatures. Natural rubber won’t melt in the same way, but repeated heat exposure can still cause it to dry out, weaken, and lose recovery over time.
Ironing may temporarily improve the appearance of slightly stretched elastic by helping fibres relax back into place — but if the fibres have been damaged the lifespan of the elastic can be shortened.
WHY DO SOME ELASTICS STRETCH OUT WHEN SEWING?
If your elastic looks wavy or overstretched after sewing, it’s usually a sign it has been placed under too much tension or is not the right elastic for the application.
As elastic is stretched when sewn, the fibres are extended. If that tension is too high — or unevenly distributed — the elastic can begin to fatigue or distort. Tight stitching, uneven feeding, or pulling the elastic too firmly can all contribute.
To reduce this:
- Cut your elastic so that it isn't too tightly around you at rest
- Use the minimum stretch required when sewing
- Distribute tension evenly
- Avoid tight or restrictive stitching
- Choose an elastic suited to your sewing method
Construction matters too:
- Woven elastic maintains its width and structure under tension, making it ideal for sewing directly onto fabric
- Braided elastic narrows when stretched and is better suited to casings
CHOOSING THE RIGHT ELASTIC FOR YOUR PROJECT
Different elastics perform better in different situations.
We stock a range of elastics specially designed to be worn directly against the skin. Made with ultra-soft fibres and carefully considered construction methods, these elastics are exceptionally gentle and comfortable, while also helping to protect the natural rubber from the skin’s natural oils for improved longevity.

WHAT HAPPENS AT END OF LIFE?
All elastic will eventually wear out. The difference is what happens next.
Synthetic elastics are made from plastic-based fibres that persist in landfill and can contribute to microplastic pollution.
Natural elastic, when made from 100% plastic-free materials, can be safely returned to the earth. It can be cut into small pieces and added to your compost, where it will break down without leaving harmful residues.
