The idea of wearing the same piece to the gym, the pool, and the sauna sounds like it shouldn't work. With 96% merino, it does.
Most activewear is designed with one environment in mind. You train in it, perspire in it, and then change out of it. The idea that a single piece could carry you from a gym session, yoga mat, or pilates studio to open water — without compromise — isn't something the synthetic-dominated activewear industry has had much reason to explore.
Swimm has.
The Gymm to Swimm range is built on the same 96% merino-elastane blend that underpins every Swimm piece. Not a different fabric, not a watered-down version — the same material, rethought for movement on land as well as in water.
Why merino works where synthetics don't
Synthetic activewear is functional, but it comes with trade-offs. It holds odour. It traps heat unevenly. And in water, it clings.
Merino wool regulates temperature naturally — warming when you need it, releasing heat when you don't. It's inherently odour-resistant, which matters when you're moving between environments. And unlike most synthetic swimwear, it doesn't cling when wet.
It's also fully biodegradable. What you wear into the water doesn't leave a trace when it's done.
Designed for the transition
The pieces in the Gymm to Swimm range are cut for movement — squats, stretches, sun salutations, laps. They don't require a change of kit between your last rep and the pool. The water doesn't change how they feel. The gym, yoga studio, or pilates class doesn't compromise how they perform in it.
This isn't a marketing concept. It's a material one.
The sauna, too
Merino's temperature regulation makes it equally suited to heat. Where synthetic fabrics can feel uncomfortable or restrictive in a sauna, merino breathes. The Gymm to Swimm range moves through the full circuit — gym, yoga, pilates, water, sauna — without needing to be swapped out.
A note on the fabric
The 96/4 merino-elastane blend used in every Swimm piece took three years to develop. Different ratios, different knit structures — tested in chlorinated pools, heated pools, open water. It wasn't released until it was right.
The Gymm to Swimm range is the same standard, applied to a wider context.
