Plastic-Free Contact • Nature-First • Performance-Driven
3.5" Inseam | 100% Wool Body | Minimal Synthetic Touchpoints
These aren't your average shorts—they're a shift in what performance wear can be.
Made from 100% extra fine merino wool (19.5 microns, 250 GSM), these warm-up shorts deliver breathable comfort, natural temperature control, and unmatched versatility—without relying on petroleum-based fabrics.
Perfect for training, hiking, lounging, or layering. Designed for movement and made with mindfulness.
Plastic-Free Contact – The body fabric is 100% wool; no synthetics touch your skin
Breathable & Temperature-Regulating – Naturally cool in heat, warm in cold
Odor-Resistant – Stays fresh even through intense sessions
Preshrunk & Washer-Safe – Easy-care, worry-free washing
Functional Fit – Handwarmer pockets + elastic waistband with interior drawstring
While the main fabric is 100% merino wool, a few functional elements include:
Elastic waistband (includes internal elastic drawstring)
Zipper lining (nylon coil for durability and flexibility)
We use synthetics only where necessary—and we’ll always tell you exactly where and why.

Most athletic wear is made with polyester, nylon, or spandex—synthetics that shed microplastics and persist in landfills for centuries.
These shorts do the opposite:
They’re biodegradable, naturally high-performing, and part of a growing movement toward cleaner clothing with nothing to hide.

These are perfect! Comfortable, dry, both warm and cool, odor control.
I used to cycle in the 80's and there was a brand of cycling shorts called Protogs. When the chammy liner wore out I wore them as non-cycling shorts. I've been looking for similar shorts since then. I'm very glad to have found Roanhorse. I bought a 2nd pair immediately.
Super soft comfortable shorts! Great quality and cut / fit which can be hard to find, especially.in all natural materials. Nicely done!
Super soft! Love them so far
Great fit and comfort, wear them every night to bed.
