Merino Bikini Underwear – Women's

For active women who need underwear that keeps up across long days, trail runs, and travel, the Merino Bikini is our go-to pick for everyday performance. Merino wool naturally regulates temperature and resists odor, so you stay fresh whether you're logging miles or miles of airports. The low-profile bikini cut layers cleanly under anything without bulk.

• Merino wool blend wicks moisture and resists odor naturally — no synthetic treatments needed
• Lightweight, stretchy knit moves with you without binding or bunching
• Low-rise bikini cut sits low-profile under leggings, shorts, or casual wear
• Soft elastic waistband stays put without digging in during high-output activity
• Available in Black, Twilight Blue, and Light Gray Heather — sizes XS through XL
