Cut to flatter
Every angle.
- Cut higher at the back so it lifts instead of flattens.
- A gathered seam at the back that hugs the curve.
- A touch more coverage at the crotch, so you can sit easy in the sauna.
- Stretch from natural rubber cords, not plastic elastic.
Body luvin' fabric.
Soft on your skin
Ultrafine merino fibers feel soft against your skin. Merino dries quickly, so it doesn't stay damp between rounds.
Smells fresh, easy to wash
Merino is naturally odor-resistant, so it stays fresh between wears. When it does need a wash, use cool water and a light wool detergent, then lay it flat to dry.
Breathes in the heat
Research published by the NIH found merino absorbs and releases moisture vapor efficiently, keeping the air next to your skin drier and more stable.
Why we quit synthetics.
Most swimwear is made from polyester, nylon, elastane, lycra and spandex. Despite the different names, they are all petrochemical derived synthetic fibers.
~700000
microfibers per wash
A single load of synthetic swimwear can shed hundreds of thousands of plastic fibers into the water.
190°F
plastic on skin
A 2025 study in Science of The Total Environment found polyester, nylon and spandex fabrics kept at 185–212°F broke down faster, shedding microplastics and leaching additives.

'recycled' is still polyester
Recycled polyester is made from the same polyethylene terephthalate (PET) plastic as disposable water bottles. It sheds, traps heat and holds smell exactly like virgin polyester.
EWE asked,
we answered.
Is merino wool itchy?
Conventional wool, like your grandma's sweater, is around 30 microns thick. Merino wool sits under 18 microns thick and is much softer and more bendable, so it doesn't poke your skin.
Can I wear this to the pool, beach, and hot tub?
Yes, yes and yes.
Chlorine is a harsh chemical for all fabrics and will naturally break down even synthetic fabrics after repeated, prolonged exposure (e.g. swimming in a chlorinated pool as daily exercise). Our Merino Wool Bikini Set was designed to optimize health and did not prioritize chlorine resistance.
Treat it well, rinse with a gentle wool detergent and it will last you many, many wears year round.
How do I wash it?
Hand wash on cool or with room temperature water, lay flat to dry.
Our Easy 3 Step Wash Ritual:
1. Post-sauna or pool sess, rinse while you are in the shower with a light shampoo.
2. Squeeze out water (no stretching or heavy wringing) and pat dry with a dry cotton towel. It should be at least halfway dry at this point.
3. Store in a bag with an unsealed top until you can lay it flat to dry.
Will it shrink?
Merino is a finer fiber than conventional wool and so it is less prone to shrinking. It is typical for merino to shrink 0-3% and often goes unnoticed. Please be mindful of this when selecting sizes.
Wash with cool or room temperature water. Do not wash on hot or put in the dryer to prevent unwanted shrinking or felting.
Can I wear it for contrast therapy?
Absolutely. That is exactly what we designed it for!
Why not recycled polyester?
Because recycled polyester is still made from the same material as virgin polyester. It actually sheds more microplastics.
When selecting for the healthiest fabric, we chose to go for nature's own performance fiber rather than undergo a process that turns hard plastic into synthetic fibers.
Do you accept returns or exchanges?
Yes. You have 30 days from delivery to exchange or return it, as long as it is unworn with the liner and tags still on. Returns are free in the US, Canada and Mexico, and a flat $20 USD everywhere else. (This fee does not cover any additional international VAT or duties.)
