Perfect for all your adventures, such as trail running, single-track laps, boulder projects, or your next HIIT session, this bra moves with you wherever your day—or your workout—takes you.

5/13/26: Updated fit guidance
To find your best fit, start with the band—our sizing is based on field testing where two fingers fit comfortably between the band and your body, but not more.

Because this fabric is more compressive than our everyday bras, women with a fuller bust and smaller ribcage may prefer to size up 1–2 sizes for their ideal balance of support and comfort.

If you prefer a slightly less compressive feel overall, we also recommend sizing up.

Care Guide:

We recommend using a mesh cotton laundry bag to protect the straps and reduce stretching and stress on the fabric. Hand or machine wash with like colors in cool water with a wool-friendly soap, then hang 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 ethically-sourced Merino wool is ZQRX™-certified. Our factory is located in Europe.

Each piece is knit seamlessly on Santoni machines 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.

PERFORMANCE WITHOUT COMPROMISE

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.
