Merino Wool Sauna Bath Suit

A modern nod to the classic wool bathing suits of the past, the Sauna Bath Suit has vintage charm without the itch. Crafted from 100% merino wool, this one-piece suit offers ultra-soft comfort with a flattering silhouette and a breathable, non-restrictive fit designed for sauna, spa, or swim.

A built-in shelf bra provides gentle support and structure, making this suit as functional as it is timeless. The soft wool knit hugs the body without clinging, allowing your skin to breathe and move freely.

Unlike synthetic bathing suits that trap heat and moisture, the Bath Suit is made from natural, microplastic-free fibers that support temperature regulation in high heat—making it the ideal companion for sauna sessions and beyond.

Style Tip

The Bath Suit pairs beautifully with our Lounge Pants, creating a breathable, flexible set ideal for gentle movement, stretching, or post-sauna relaxation. Whether you're flowing through a morning yoga practice or unwinding after heat and cold therapy, this pairing brings ease, comfort, and timeless style to your ritual.
