Underwear Size Guide
All our knitwear has a lot of stretch, so you might be able to wear two different sizes. If you are unsure, size up.

Our Performance Innerwear is meant to fit snugly on the body. If you prefer a looser fit, we recommend sizing up. If it feels just a little tight and you aren't sure if the next size up would be better, then we recommend wearing and washing a few times to see if it breaks in to your liking before exchanging it for another size.
Not really. Our Performance Innerwear does give a bit with wear, but instead of becoming loose, it will mold to your body more over time.
50% fitted, 50% roomy, 100% amazing. This Essential Boyshort offers more generous coverage than our Hipster style, making it perfect for relaxing, working out, layering underneath, or diving into an impromptu dip. Whether you're wearing it beneath a dress or under your snow gear, it adapts to your lifestyle with remarkable ease.
Constructed from seamless Merino wool with no elastic band means zero pinching, zero slipping, zero fussing—guaranteed.Softly finished leg edges flex with your body from sunrise runs to sunset wind-downs. Impossibly smooth texture means you'll stop noticing it's there... until you realize it's become your new favorite thing.
Note on fit: Every body is beautifully different (and that's the point). How much skin gets covered shifts based on your unique frame and where you position them on your waist.
Bonus: Our exclusive GLDNspun™ technology is made fromZQ+™, RWS, and Woolmark-certified Merino fibers–making it sustainable—clear of BPA, PFAs, and other harmful "forever chemicals."
Dual Bonus: Wear these Boyshorts either hugging your hip line or lifted to sit just above your navel for a higher-rise silhouette and greater belly support.
Our medium-rise GLDNspun™ Essential Boyshort hits below the belly button and offers boxy, full-coverage on the booty.
Our Essential Boyshort runs true to size.
Care Guide:
We recommend using a mesh cotton laundry bag to reduce stretching and stress on the fabric. Hand or machine wash with like colors in cool water with a wool-friendly soap, then lay flat to dry.
On the road or in the wild? Wash with shampoo or mild soap in the shower, rinse thoroughly, roll in a towel to eliminate excess water, and hang to dry. Merino dries super quickly. Do not put it in the dryer.
IMPORTANT:
Always wash black and darker garments separately to avoid color transfer. Never use bleach or fabric softener. Bleach destroys Merino, while fabric softeners coat the fibers, minimizing their ability to manage moisture and regulate body temperature.
Garments damaged due to improper care cannot be refunded or exchanged.
Material:
Our Merino wool is ethically sourced and ZQ+™ certified. Each piece is knit seamlessly on Santoni machines in Europe and dyed in small batches. Every garment is unique, so no two pieces are exactly alike. We are very proud of our slow craft manufacturing process.
Designed for superior performance and maximum comfort—it all starts with Merino wool. Super-soft, ultra-fine Merino wicks sweat to keep you dry, fresh, and funk-free. The natural crimp of its fiber traps air so you stay cool when things heat up and keep warm when there’s a chill.

The pieces I got all fit nicely and feel comfortable- I REALLY wish they would keep more in stock and increase the color selection, since I already have multiples of all the colors that I like!
These boy shorts are perfect for a workout and cold plunge. I am 5 ft 2, 130 pounds and ordered a medium. I will definitely be ordering more!
Wish I could afford to replace all my underwear with these merino wool boy shorts right now. So comfy and easy to care for. Great for camping or travel since they can handle a couple of days without changing way better than cotton or synthetic fabric.
Those boy shorts are the bomb! They feel great, fit great and look great. I love that sea green color as well.
Love the fit and style. Would buy again in a heartbeat.
