We love Merino wool for its soft touch and its natural stretch and breathability, so we made the Boy UnderShort.



The Women’s Boy Undershort is made with our innovative Nycore™ Merino wool blend, which features the soft touch, natural stretch, and breathability of Merino wool, with the added durability of nylon. These shorts are equipped with a CyTech™ Tri-Chamois pad and non-binding waistband for an incredibly comfortable ride. The length integrates smoothly with our shorter-length Women’s Mobility Overshort.


Fabric & Construction
Nycore™ Merino Wool, 89% Merino / 11% Nylon, 160 g/m2, Elastic Waistband, Cytech HP Tri-Chamois, Made in California
Fit Notes
Sewn In California
Sewn in our home state, the California Collection takes its name from where it’s made. Its domestic production creates jobs, keeps money in the community, reduces the environmental impact of shipping and brings us closer to the process in every way. It’s more than the tangible benefits, though, that make the difference. The “Sewn in California” tag tells a story, and it’s one we’re proud of.
