Smartwool

Seamless fit, breathable mesh knit, and unbelievably soft Merino

We always think your first layer should be Merino. So upgrade your undies to the women's Seamless Bikini. Merino wool comes with a lot of natural benefits when worn next to skin, including sweat management, thermoregulation, and odor resistance. Combine that with a seamlessly knit yet supportive build and mesh knit throughout the body for breathability, and you're ready to handle whatever the day holds. And you'll do it all comfortably.
