Model shown wearing 5" inseam.
These 7-inch athletic shorts are made with 100% extra-fine New Zealand merino wool (19.5 microns, 250 GSM) for natural performance without polyester or nylon in the main body fabric.
Made with RWS-certified and OEKO-TEX® certified material, they're built for training, warm-ups, travel, recovery, and everyday movement.
Merino naturally manages moisture, resists odor, breathes, and helps regulate temperature — without relying on synthetic performance fabric or a synthetic liner.
We've also chosen a metal pocket zipper instead of a conventional plastic zipper, reducing another source of plastic in the garment.
Natural fiber where it matters most. Less plastic where we can. Built to move.
The main fabric is 100% extra-fine merino wool — not a merino/polyester blend. Soft against the skin, naturally breathable, and built for movement.
Our merino wool originates in New Zealand, one of the world's best-known regions for fine merino wool production.
The wool used in our production is RWS certified under the Responsible Wool Standard, which establishes requirements around animal welfare, land management, and traceability through the wool supply chain.
The material is OEKO-TEX® certified, providing an additional standard for textile testing and restricted harmful substances.
At 19.5 microns, the wool fibers are exceptionally fine, creating a much softer next-to-skin feel than the coarse wool many people associate with traditional wool clothing.
A substantial 250 GSM fabric weight gives the shorts structure for training and everyday wear while maintaining the natural breathability and temperature-regulating characteristics of merino wool.
Merino wool naturally manages odor, helping the shorts stay fresher between washes — especially useful for training, travel, and repeated wear.
Merino helps your body remain comfortable across changing conditions, whether you're warming up, training, traveling, recovering, or simply moving throughout the day.
There is no polyester or nylon performance liner sitting against your body. The merino short itself becomes the primary next-to-skin layer.
The 7-inch inseam provides more coverage than our shorter athletic cut while maintaining freedom of movement. It's a versatile length designed to work in the gym, outdoors, while traveling, or throughout everyday life.
Instead of using a conventional plastic pocket zipper, these shorts feature a metal zipper, eliminating another unnecessary plastic component from the garment.
It's a small detail, but that's how we approach reducing synthetics: component by component, wherever a better alternative makes sense.
Useful handwarmer pockets provide everyday functionality without turning the shorts into overly technical activewear.
An internal elastic waistband and drawstring provide a secure, comfortable fit while allowing the merino body to remain naturally flexible.
When we say 100% merino wool, we're talking about the main body fabric.
We don't believe in pretending every component of a finished performance garment can currently be made entirely from wool.
Small amounts of synthetic material are still used where functionally necessary, including:
But we're actively looking for places where plastic can be removed.
That's why these shorts use a metal pocket zipper instead of a conventional plastic zipper.
What you won't find is a polyester or nylon body fabric disguised behind a small percentage of merino. And you won't find a synthetic athletic liner underneath the wool.
The fabric covering the overwhelming majority of your body is 100% merino wool.
We're reducing synthetics wherever we reasonably can — from the body fabric to smaller components like the zipper — and being transparent about where we haven't eliminated them yet.

Measurements represent typical body measurements in inches. For the best fit, measure around your natural waist. If you're between sizes or prefer a more relaxed fit, consider sizing up.
Most modern athletic shorts are made primarily from polyester, nylon, elastane, or blends of synthetic fibers.
Those materials can perform extremely well — but they're not the only way to build performance clothing.
Merino wool gives you a natural alternative.
It is naturally:
Instead of taking merino wool and blending it heavily with polyester to make it behave like conventional activewear, we wanted the wool itself to do the work.
That's why the body of these shorts is 100% merino wool.
No polyester body.
No nylon body.
No synthetic liner.
Metal zipper instead of plastic.
Just substantial 250 GSM, 19.5-micron New Zealand merino wool where your clothing spends the most time against your skin.
