For comfort, bamboo-based viscose is naturally smooth, breathable, and great at moisture management—which often means cooler skin and less irritation than many basic cotton knits. For impact, bamboo is a fast-growing, renewable plant that typically needs less water and fewer inputs than conventional cotton crops. Combine that with durable construction and you replace underwear less often, which further shrinks your footprint.
In short: softer feel, better all-day comfort, and a materials choice that supports our goal of better basics with a smaller impact.
