Why
merino?
We tested every natural fiber and landed on merino as the backbone of our fabrics because of how well it regulates temperature, wicks sweat to keep you dry through longer sessions, and is naturally antimicrobial. It addresses every point of failure we found in conventional swimwear for contrast therapy.
The blend is merino and lyocell — lyocell adds lightness, softness, and moisture management without relying on synthetic treatments. The result is a garment that performs better the more seriously you use it.
01
Merino
Natural thermoregulation and inherent odor resistance without coatings.
02
Lyocell
Lightweight, breathable, and built for rapid wet-dry cycles.
03
Superfine
Comfortable directly against skin at heat. No itch, no texture compromise.
04
No coatings
Performance through fiber, not surface treatment. Nothing to wash away.
