Merino wool swimwear is an investment. With the right care, it'll last for years — here's exactly what to do.
The basics
Merino is hardier than its reputation suggests, but it does need a little more attention than polyester. The good news: the routine is simple once you know it.
- Rinse immediately after use — saltwater, chlorine, and sunscreen are the main enemies. A quick cold rinse after every swim removes them before they can break down the fibres.
- Hand wash is ideal, but a gentle machine cycle on cold works fine. Use a wool-specific detergent or a gentle, pH-neutral soap. Avoid anything with enzymes or bleach.
- Never wring or twist — merino fibres are delicate when wet. Gently press out excess water instead.
- Lay flat to dry — always. Hanging wet merino stretches it out of shape. A flat surface in the shade is ideal; direct sunlight can fade colour and weaken fibres over time.
What about the dryer?
You can use the dryer on the lowest heat setting — it won't ruin it. But repeated heat exposure will shorten its lifespan over time, so air drying flat is always the better option when you have the time.
Chlorine and saltwater
Merino handles both well, but prompt rinsing is key. If you're swimming laps regularly, a cold rinse immediately after each session is the single most important thing you can do to extend the life of your swimwear.
Storage
Store clean and dry, folded rather than hung. If storing for a season, keep in a breathable bag away from direct light.
The payoff
Follow these steps and merino wool swimwear will outlast most synthetic alternatives by years. The fibres are naturally resilient, the construction is built to last — the care routine is just about protecting what's already there.
