What is TENCEL™ Modal?
This eco-friendly fabric starts its journey in the eucalyptus forests, where tree pulp is magically transformed into soft, breathable yarn through a process so green, it practically hugs the planet. With a 99% solvent recovery rate, this "closed loop" system means you're wrapped in sustainability. Blended with a touch of spandex, our fabric is like the love child of cotton and linen—stretchy, natural, and ridiculously comfy.

Absolutely love the fact that I'm wearing something healthy for my body and sustainable for both me and the planet. Unfortunately the briefs weren't the best fit for me. I prefer a little bit of a higher waist whereas these made me feel like they were about to constantly fall down. The crotch area also felt a bit baggy and was a stark contrast in material from the rest of the brief which is otherwise soft and comfy.
