We always think your first layer should be Merino. So upgrade your undies to our Women's Intraknit 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.
